Consider a reheat Rankine cycle with a net power output of 100 MW. Steam enters the high pressure turbine at 10 MPa and 500°C and the low pressure turbine at 1 MPa and 500°C. The steam leaves the condenser at 10 kPa. The isentropic efficiencies of turbine and pump are 80% and 95%, respectively. Part 1 1. Show the cycle on a T-S diagram with respect to saturation lines. 2. Determine the mass flow rate of steam. 3. Determine the thermal efficiency for this cycle. 4. Determine the thermal efficiency for the equivalent Carnot cycle and compare it with the Rankine cycle efficiency.

Box your final answers. PROBLEM 5 A coke packed humidifier is to be designed to cool 3,000 cfm of saturated air from 150 to 75 °F at barometric pressure. Cooling water at 50°F will be allowed to heat up to 100°F. Gas velocity will be 3,000 lb of dry air per sq ft of total cross section. Water velocity is 1,200 lb/h per sq ft of total cross section. Over-all coefficient of sensible heat transfer from air to water = 300 BTU/h·ft3·°F. Calculate the height and diameter of cooling tower required. Round your answers to the nearest 0.05 ft.
