Four pounds of air gain 0.491 Btu/R of entropy during a nonflow isothermal process. If p1=120 psia and V2=42.5 ft3, find (a)V1 and T1, (b) W, (c) Q and (d) change of internal energy.
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.

A curious blacksmith forge 1 kg of iron then dropped it to an insulated container that contains 50 liters of water. Before dropping the iron into the insulated container, the blacksmith measures the temperature of iron and water as 500 °C and 20 °C, respectively. This curious blacksmith is always interested in thermodynamics and tries to calculate equilibrium temperature and the total entropy change because of his/her action. What will be the equilibrium temperature and the total entropy change? Is this process reversible or irreversible? (Density and specific heat of water at 20 °C are 995.10 kg/m3 and 4.16 kJ/kg.C, respectively. Assume that the specific heat capacity of iron is 0.5 kJ/kg.C)
