An insulated pump receives liquid engine oil (density ρ = 55 lbm/ft3 , specific heat c = 0.442 Btu/lbm-R) at 75 oF and 15 psia, and exhausts the oil at 3000 psia and 140 oF. The mass flow rate of the oil is 1.2 lbm/s. Determine the power required by the pump.

For liquid benzene at 25 ̊C, the specific heat at constant pressure is 1.78 J K-1 g-1, the density is 0.88 g cm-3, the coefficient of thermal expansion is 0.00124 K-1, and the isothermal compressibility is 9.8x10-5 atm-1. Calculate the molar heat capacity of benzene at 25 ̊C, at constant pressure and at constant volume.
