question

A fluid having a flow rate of 5lbm/sec passes through a pipe where heat is transferred at the rate of 50 Btu/sec. How much work can be done by this system if the velocity, enthalpy and height at the entrance are 100 ft/sec, 1000 Btu/lbm, and 100 ft respectively. At the exit the values of these quantities are 50 ft/sec, 1020 Btu/lbm, and 0 ft. What is the area of the inlet of the pipe if the specific volume of the fluid is 15 ft^3/lbm.
