A fluid at 0.7 bar occupying 0.09 m' is compressed reversibly to a pressure of 3.5 bar according to a law pv* = constant. The fluid is then heated reversibly at constant volume until the pressure is 4 bar; the specific volume is then 0.5 m/kg. A reversible expansion according to a law pe- constant restores the fluid to its initial state. Sketch the cycle on a p-e diagram and calculate: (i) the mass of fluid present; (ii) the value of n in the first process; (iii) the net work of the cycle.

I am getting lost in this practice problem for thermodynamics - thank you! Air at 100 kPa and 280K is compressed steadily to 600 kPa and 400K in an air compressor. The mass flow rate of air through the compressor is 0.02 kg/s and the compressor a heat loss of 16 kJ/kg from the compressor occurs. Assuming steady state steady flow conditions and ideal gas behavior (with constant specific heats, Cp=1.009 kJ/kgK, R=0.287 kJ/kgK, determine: a) The necessary power in put to the compressor(kW).b) The volumetric flow rate of air at the exit of the compressor (m3/s).

A closed system contains an ideal gas, which molecular weight is W = 63.47 kg/kmol, and its standard state entropy is S0 = 0. The system undergoes the following cycle: at state 1 the temperature is 295.15 K, the pressure is 95 kPa (absolute), and the entropy is 46.450 J/(kg/kmol). The gas is compressed polytropically at n = 1.46 until the specific volume is 10 times lower than that at state 1 ( state 2 ). Then 85651.7 J/kg of heat is added at constant specific volume ( state 3). After that heat is added at constant pressure until entropy is 333.333 J/(kg.K) (state 4). In the next process the system undergoes isentropic expansion (and reaches state 5 ). Finally there is a constant volume rejection of heat (until state 1). Determine a) the values of p, v, T and s, at each cycle point; b) the p-V and T-s diagrams of cycle; c) the heat added to the system; d) the heat rejected by the system; e) the cycle net work; f) the mean effective pressure; g) the cycle thermal efficiency.
