Item Biomass charcoal making by briquetting machine(AIKTC, 2021-05) Karve, Amruta; Ansari, Mohammad Fahad Nisar Ahmed (18DME04); Ansari, Tanvir Mohammed Javed (18DME07); Khan, Sohel Ahmed Siraj Ahmed (18DME21); Pawaskar, Sufyan Aslam (18DME30)This report investigates the innovation, execution, and conceivable commercialization of charcoal briquettes obtained from dry organic waste through heat treatments in developing markets. Given the absence of formal and unified waste administration framework in developing markets, we present a minimal effort heat treatment framework to deliver charcoal briquettes obtained from dry organic waste. Bio-absorption, and other waste-to-energy advancements address potential answers for this issue, but because of mechanical, infrastructural, and transportation reasons these innovations have not hit the necessary scale to handle the huge volume of organic waste produced in metropolitan territories. With absence of framework or innovation for legitimate decomposing or reusing, organic waste addresses practically no money related incentive for cooperatives who work and fill in as true waste gatherers from metropolitan households. The briquetting innovation accessible is for the most part for the upscale business and for large scale manufacturing and which isn't feasible for the macro-associations or an individual we have likewise proposed an answer for it in this report which is prudent and attainable for such associations or a person.Item Design and installation of VRV system(AIKTC, 2021-05) Karve, Amruta; Siddiqui, Ahsanuddin Qamruddin (18DME53); Shaikh, Abdul Gani Abdul Gaffar (18DME40); Khan, Mohd Irshad Mohd Safique (18DME18); Shaikh, Shoaib Mohd Ayaz (18DME50)Air conditioning demand is rapidly increasing in many parts of the world especially in moderate climate. Air conditioners and refrigerators are the only equipment consumes more electricity say 70 percent house hold articles this result in drastic electricity demands on hot summer days which causes unwanted increase in the use of fossil fuel and nuclear energy which leads to global warming and air pollution. The VRV system uses R410A as refrigerant because it contains only Fluorine hence it has very low global warming potential. VRV systems are enhanced versions of ductless multi-split systems, permitting more indoor units to be connected to each outdoor unit and providing additional features such as simultaneous heating and cooling and heat recovery. VRV technology uses smart integrated controls, variable speed drives, refrigerant piping, and heat recovery to provide products with attributes that include high energy efficiency, flexible operation, ease of installation, low noise, zone control, and comfort using all-electric technology. VRV systems are very popular in Asia. This thesis presents design of Variable Refrigerant Volume (VRV) system for a residential building in Four Seasons Residency Worli Mumbai. The VRV system was selected as the space saving was priority of the client. The system is designed using ISHRAE hand book and DAIKIN manual. The heat load was calculated considering various factors such as outdoor condition, heat gain through glass, transmission gain through wall etc. As per the heat load calculated proper selection of outdoor unit and indoor unit was done using DAIKIN manual. The schematic of pipe and indoor is displayed considering cost effectiveness. The obtained results were validated by the industry. Keywords: R410A, ISHRAE, outdoor unit, indoor unit, cassette, British Thermal Unit, compressorItem Design, fabrication and development on single car test rig used for pneumatic air break testing in railways(AIKTC, 2020-05) Karve, Amruta; Meman, Afajal Valeemahamad (12ME34); Siddique, Mohd Mohsin (15ME112); Siddiqui, Tausif Baharuddin (15ME110); Surme, Kashif Khalil (12ME79)Reliability and increased asset utilization has been the focus of railroads, particularly in heavy haul operations. The maintenance principles have shifted from time-based criteria to condition based criteria with periodic testing. The ability to accurately test, diagnose and repair the brake system of a freight car has obvious benefits to maintainers and operators. The deficiencies and subjectivity of manual testing has given way to the introduction of Automated Single Car Testing. This book will review the benefits of automated single car testing. Data will be presented analyzing brake equipment failure modes.Item Experimental investigation on forcedconvection heat transfer augumentation using annular blockages(AIKTC, 2017-04) Karve, Amruta; Pawar, Siddhesh; Patel, Farhan; Shaikh, Dishan; Mugal, ApsarHeat transfer intensify techniques ( Passive, Active & Compound methods ) are commonly used in areas such as process industries, heating and cooling in evaporators, thermal power plants, air-conditioning equipments, refrigerators, radiators or space vehicles, automobiles, etc. Passive techniques, where inserts are used in the flow passage to intensify the heat transfer rate, are advantageous compared with active techniques, because the insert manufacturing process is simple and these techniques can be easily employed in an existing heat exchanger. In design of compact heat exchanger, passive techniques of heat transfer augmentation can play an important role if a proper passive insert configuration can be selected according to the heat exchanger working condition ( Both flow and heat transfer conditions ). Many researchers have used different passive methods to improve heat transfer. Passive heat transfer methods are not only applicable in heat exchanger but also in solar air heater and cooling of electronic components. Experimental work on heat transfer augmentation using annular blockages. Inserts when placed in the path of the flow of the fluid, create a high degree of turbulence resulting in an increase in the heat transfer rate and the pressure drop. The work includes the determination of friction factor and heat transfer coefficient for various annular blockages and annular blockages having different diameter. The results of annular blockages having different diameter have been compared with the values for the plain tube. Four annular blockages (di=20%, 30%, 40% reduction in outer diameter) are used in the study.Item Forming process(AIKTC, 2016-09-23) Karve, AmrutaeCourseware: This PPT Slide Show Covers Topic From Production Process I In Semester III, B.E. Mechanical Engineering.Item Heat transfer augmentation using passive technique(AIKTC, 2017-04) Karve, Amruta; Idrishi, Shadab (13ME21); Shaikh, Saquib (13ME49); Chaudhary, Umair (14DME126)Energy and materials saving considerations, as well as economic incentives, have led to efforts to produce more efficient heat exchange equipment. Common thermo hydraulic goals are to reduce the size of a heat exchanger required for a specified heat duty, to upgrade the capacity of an existing heat exchanger, to reduce the approach temperature difference for the process streams, or to reduce the pumping power.Item Plastic waste management(AIKTC, 2018-05) Karve, Amruta; Kewal, Zaid (15DME127); Faisal, Farid(15MDE125); Don, Umar(15DME145); Shemle, Farzan(15DME157)The present rate of economic growth is unsustainable without saving of fossil energy like crude oil, natural gas, or coal. There are many alternatives to fossil energy such as biomass, hydropower, and wind energy. Also, suitable waste management strategy is another important aspect. Development and modernization have brought about a huge increase in the production of all kinds of commodities, which indirectly generate waste. Plastics have been one of the materials because of their wide range of applications due to versatility and relatively low cost.Item Re-engineering existing plastic product with biodegradable material(AIKTC, 2022-05) Karve, Amruta; Ansari, Asif Raza Md Mehmood Alam (18ME05); Ansari, Salman Salahuddin (18ME10); Khan, Ahmad Iftekhar Ahmad (18ME35); Thanwal, Adna Mujaheed (18ME57)The Toothbrush has been an integral part of a daily routine across many cultures around the world in the 21st century. Numerous types of toothbrushes have been developed over time. A toothbrush is used to clean the teeth, gums, and tongue. Around 99% of toothbrushes in the world are made from plastic. While plastics have many valuable uses, humans have developed a dependence on disposable plastic, which has a serious impact on the environment. Half of all plastic produced is intended to be used once and then discarded. Plastic garbage has become so pervasive in the natural world that it has devolved into the trash and has had far-reaching consequences. Observing the current environmental consequences, it is necessary to make environmentally friendly toothbrushes. This project aims to replace plastic with biodegradable materials which can decompose in nature without ruining the environment. During the current state of the world, the project focus to make biodegradable toothbrush body from waste and bristle from bioplastic and encourages activities to make use of biodegradable material making and using.
