A fluid at X bar of 0,733 occupying 0.09m^3 is compressed reversibly to a pressure of Y bar of 11 and a specific volume of Z=0.55m^3/kg according to the law of Pv^n=c. The fluid then expands reversibly according to the law Pv^2=c to the value A bar of 2,2.A reversible cooling at constant volume then restores the fluid back to initial state. Calculate (a) mass of the fluid present;(b) the value of n in the process ;(c) the network of the cycle and (d) Sketch the P-v diagram for the cycle.
For a certain gas R = 320 J/kg*K and cv = 0.84 kJ/kg*Kc (a) Find cp and k, (b) If 5 kg of this gas undergo a reversible non flow constant pressure process V1 = 1.133 m3 and p1= 690 kPa to a state where t2 = 555ᵒ C, find ∆U and ∆H
When a system undergoes a Isochoric process (P = 5 bar), the change in internal internal is 5 kJ and temperature during the process is 15°C. Then its change in entropy would be approximately 1.736 kJ/kgK
