Question

_{consider a piston-cylinder assembly that operate in isobaric process. steam undergoes the process from 400C to reach 900C. Select two different values of pressure in the range of 5 to 20 MPa at which the preocess is undergoing and subsequently plot the heat transfer (kJ/kg) as a function of the chosen pressure values.}
