A steady-state, steady flow thermodynamic system receives 100lb/min of a fluid at a 30psia and 200°F and discharges it from a point 80ft above the entrance section at 150psia and 600°F. The fluid enters with a velocity of 7200ft/min and leaves with a velocity of 2400ft/min. During this process, there are supplied 25000BTU/hr of heat from an external source, and the increase in enthalpy is 2.0BTU/lb. Determine the work done in horsepower. The answer is 5.48Hp. Who can give me the solution?
