2200K. Compute the following: (a) the temperature at the end of the compression process, (b) the volumetric compression ratio of this engine, (c) the amount of work done during the compression process per kg of air, (d) the temperature at the end of the expansion process, (e) the net work of the cycle per kg of air, and (f) the cycle thermal efficiency. Assume air to be an ideal gas with constant specific heats [Cp, o=1.004 kJ/(kg K) and Cv, o=0.717 kJ/(kg K)]. Also, assume that the compression and expansion processes are isentropic.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
