Steam enters a counterflow heat exchanger operating at steady state at 0.07 MPa with a quality of 0.9 and exits at the same pressure as saturated liquid. The steam mass flow rate is 1.3 kg/min. A separate stream of air with a mass flow rate of 100 kg/min enters at 30oC and exits at 60oC. The ideal gas model with cp = 1.005 kJ/kg·K can be assumed for air. Kinetic and potential energy effects are negligible. Determine the temperature of...

A stream containing ethane gas (C2He) enters the inner pipe of a double-pipe heat exchanger at 40°C and 105 kPa and exits from the pipe at 240*C and the same pressure. Superheated steam at 315 C and 5.0 bars enters the outer (annular) pipe, flowing counter-currently to the ethane, and exits as a saturated vapor at the same pressure. Neglecting the heat losses from the heat exchanger to its surroundings. Draw a diagram of the process. (5) What are the...

Problem 3 Steam enters a heat exchanger at 0.1 bar with a quality of 0.95 and condensate exits at 0.1 bar and 45'C. Cooling water enters the heat exchanger in a separate stream as a liquid at 20'C and exits as a liquid at 35 C with no changes in pressure. Heat transfer from the outside of the heat exchanger and changes in the kinetic and potential energies of the flowing streams can be ignored. For steady state operation, (a)...

Refrigerant 134a enters a compressor with a mass flow rate of 15 kg/s with a velocity of 10 m/s. The refrigerant enters the compressor as a saturated vapor at 10°C and leaves the compressor at 1400 kPa with an enthalpy of 281.39 kJ/kg with a negligible velocity. The rate of work done on the refrigerant is measured to be 380 kW. If the elevation change between the compressor inlet and exit is negligible, determine the rate of heat transfer associated...
