please answer the above question (all parts)

Assume the system maintains the mass rate for all questions. a) What is the exit enthalpy of the pump? Temperature? Remember integration by parts: abudv=uvababvdu b) How much heat must be added to the system in the boiler (square after pump)? c) What is the velocity at the outlet of the nozzle? Assume a pipe diameter of 0.25m. d) What is the maximum velocity an outlet nozzle in this problem could produce? Justify your answer. What is the kinetic energy? (Ignore entropy for this problem)
