Dear Mr Candidate requiring answers,
your problem will require compression factor of R-134a vapors and in second problem will require data on expansion of rubber tube in the car tyre. these data once searched or received, your problem will be solved in a very small time.
I shall be very interested to solve such problems in future also as I have taught thermodynamics to Engineering Students for more than 10 yrs. I am providing my brief introduction as follows:
I have B. Tech. ( Chemical Engg.) from HBTI Kanpur, M. Tech. (Chemical Engg.) form IIT Kanpur and PH. D. from University of Wollongong, Wollongong, N.S.W. Australia and have been recipient of National Scholarship, Government of India and Post Graduate Award by Australian Iron & Steel, Port Kembla, NSW Australia.
I worked with Indian Explosives Ltd (Sister Concern of ICI, UK), Kanpur, manufacturing Urea and with Australian Iron & Steel, Port Kembla, NSW Australia towards development of a model for charging of burden material in Bell less Blast furnace No. 5 for their plant. I studied in detail mixing and segregation of particulate matter in my working model of Bell less blast furnace and in prototype of actual blast furnace using various techniques including high speed photography. I developed techniques to take representative sample from prototype model. The sample weight ranged up to 2 tons. I also worked with Nirma Group of Industries towards process improvement and waste reduction and good housekeeping practice
