4. Steam flows steadily through a turbine at a rate of 47,000 lbm/h, entering at 1000 psia and 800°F and leaving at 6 psia as saturated vapor. If the power generated by the turbine is 3.7 MW, determine the rate of heat loss from the steam.
3. Water enters the constant 125-mm inside-diameter tubes of a boiler at 7.5 MPa and 60°C and leaves the tubes at 6 MPa and 500°C with a velocity of 75 m/s. Calculate the velocity of the water at the tube inlet and the inlet volume flow rate.
2. A piston-cylinder device contains 2.4 kg of nitrogen initially at 120 kPa and 27°C. The nitrogen is now compressed slowly in a polytropic process during which PV1.3 = constant until the volume is reduced by one-half. Determine the work done and the heat transfer for this process.
