Question

Equation (1.8): Tds = dh - vdp [Btu/lbm | kJ/kg]

Use Equation (1.8) to derive an expression for the finite enthalpy change of an incompressible fluid in an isentropic process. If the process is the pressurization of saturated water initially at 250 psia, what is the enthalpy rise, in Btu /lbm and in ft-lbf / lbm, if the final pressure is 4000 psia? What is the enthalpy rise if the initial pressure is 100 kPa and the final pressure is 950 kPa?

please if you do not know how to answer do not answer
