A steam generation unit in power plant operates at a constant pressure of (10 bar) and the water evaporates at the rate of (0.9 from the total mass flow rate of water). Inlet and leaving water enthalpy are (200 kJ/kg) and (2000 kJ/kg) respectively. The inlet and outlet velocity are (10 m/s) and (25 m/s) respectively. If 80% of the heat energy supplied to the steam generation unit is used in evaporating the fluid. Determine the heat evaporation and work done if the inlet and outlet diameter are the same level. The fuel produces 28000 kJ of heat energy for one kg and the mass flow rate of water is 1000 kg/h.

Good day. I am trying to review for examinations and require assistance for these questions... IHP: Under normal atmospheric conditions, a 6-cylinder engine has a bore of 6.28 inches and a stroke of 3.5 inches with an IMEP of 400 psi at 1825 rpm. Calculate the Indicated Horsepower of the engine in watts? BHP: Compute the brake horsepower of a four-cylinder engine that has a crankshaft turning at 2,500 rpm and a torque of 750 ft.lbs BMEP: Find the brake mean effective pressure of the Pratt and Whitney 14 cylinder engine having a 6 in stroke with a piston displacement of 1 litre and produces a torque of 84 N.m. with 3000 rpm. **Would appreciate a detailed explanation. Thank you so much.
