Propane gas enters a continuous adiabatic heat exchanger 240°C. Superheated steam at 300 C and 5 bar enters the exchanger flowing countercurrently to the propane and exits as a saturated liquid at the same pressure at 40 C and 250 kPa and exits at Taking flow chart. Include both mass and volumes on your inlet and outlet streams. b. Calculate the specific enthalpy values for the inlet and outlet streams. c. Use an energy balance to calculate the required mass...

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...

3-40 In the condenser of a steam power plant the steam from the turbine enters the condenser at 0.10 bar with a quality of 95 percent and leaves at the same pressure as a saturated liquid. The steam is condensed by transferring heat to a stream of cooling water which enters at 1.3 bars and 5°C and leaves the heat exchanger at 1.2 bars and 25°C·The environmental temperature is 5°C. Determine a. the change in stream availability (exergy) of the...
The figure below provides steady-state data for a throttling valve in series with a heat exchanger.
The figure below provides steady-state data for a throttling valve in series with a heat exchanger. Saturated liquid Refrigerant 134a enters the valve at a pressure of 9 bar and is throttled to a pressure of p2 2 bar. The refrigerant then enters the heat exchanger, exiting at a temperature of 10°C with no significant decrease in pressure. In a separate stream, liquid water at 1 bar enters the heat exchanger at a temperature of 25°C with a mass flow...

PROBLEM 3 (45 points) The condenser of a large steam power plant is a heat exchanger in which steam is condensed to liquid water. Assume the condenser to be a parallel flow shell-and-tube heat exchanger consisting of a single shell and 1x10 tubes, each executing two passes. The inner diameter of tubes is D = 50 mm and its thickness is 5 mm (Do not ignore the thickness). The steam condenses on their outer surface. Thermal conductivity of the tube...
