Three kg of gas in a piston–cylinder assembly undergo a process during which the relationship between pressure and specific volume is Pv0.5=constant. The process begins with P1=250 kPa and V1=1.5 m3 and ends with P2=100 kPa. Determine the final specific volume, in m3/kg.

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines
