Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of "84" m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 14 kw from the compressor to its surroundings. assuming the ideal gas model for air and neglecting kinetic and potential energy effects, determine the power input, in kw.

On a average work day more than work place firs are reorted

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
