Calculate the compression ratio of an engine with a stroke of 1.5 inches, a bore of 3.8 inches and a clearance volume of 1.25 cubic inches. discuss whether or not this a realistic compression ratio for a street engine and what type of fuel it would need to run correctly. would this engine be considered under-square or over-square?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
