Saturated water vapour at 200°c is contained in a cylinder fitted with a piston. the intial volume of the steam is 0.01 m. the steam expands in a quasiequilibrium isothermal process until the final pressure is 200 kpa and in so doing does work against the piston. how much work is done during the process ? how much error would be made by assuming the steam to behave as an ideal gas?

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Most leaks in reciprocating air compressors can be detected and minimized by: (clo4) a)-detecting leakage areas using ultrasonic acoustic detector. b)-tightening joints and connections c)-replacing faulty equipment d)-all of the given options

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
