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...

An adiabatic heat exchanger is one for which no heat is exchanged with the surroundings. All of the heat lost by the hot stream is transferred to the cold stream in this adiabatic process. In a proposed process, propane gas enters a continuous adiabatic heat exchanger at 45 °C and 265 kPa and exits at 255 °C. Superheated steam at 300 °C and 7.0 bar enters the exchanger flowing countercurrently to the propane and exits as a saturated liquid at...

Homework 2 Problem 1: A piston-cylinder device initially contains 0.35-kg steam at 3.5 MPa, superheated by 7.4 C. Now the stream loses heat to the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid water. The cooling continues until the cylinder contains water at 200C. Determine (a) the final pressure and the quality (if mixture), (b) the boundary work, (c) the amount of heat transfer when the piston first hits...

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...
