Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

An ammonia compressor has a 5% clearance volume and displacement rate of 80 l/s and pumps against a condensing temperature of 40°c. for two different temperatures of -10°c and 10°c, compute the mass flow rate of refrigerant assuming the clearance volumetric efficiency applies. discharge specific volume corresponding to-10°c and 10°c are 112.5 l/kg and 95 l/kg, respectively.

Asteam turbine is supplied with steam at 28bar and 425c. a fraction of the steam is extracted at 1.2bar to heat the feed water in one open feed water heater. the rest of the steam expands in the low pressure stage of the turbine to 0.08bar. a)-sketch the regenerative rankine cycle with open feed water heater on the t-s diagram. b)-assuming isentropic expansion in both stages of the turbine, find the cycle efficiency. do not assume negligible pump work.
