Steam enters a horizontal pipe operating at steady state with a specific enthalpy of 1,671 kJ/kg and a mass flow rate of 0.5 kg/s. At the exit, the specific enthalpy is 2,162 kJ/kg. If there is no significant change in kinetic energy from inlet to exit, determine the rate of heat transfer between the pipe and its surroundings, in kW.
Problem 7.32 Heating Ethane with Steam Saturated steam at a gauge pressure of 3.00 bar is to be used to heat a stream of ethane. The ethane enters a heat exchanger at 16°C and 1.5 bar gauge pressure at a rate of 895 m3/min and is heated at constant pressure to 93°C. The steam condenses and leaves the exchanger as a liquid at 20.0°C. The specific enthalpy of ethane at the given pressure is 941 kJ/kg at 16°C and 1073...
Example A steam turbine receives steam with a specific enthalpy of 3121 kJ/kg. The steam leaves the turbine with a specific enthalpy of 2676 kJ/kg. The steam enters and leaves the turbine with velocities of 15 m/s and 60m/s. The elevation difference between the entry and exit ports is negligible and the heat energy lost through the turbine walls is 7600 kJ/h. Calculate the power output if the mass flow through the turbine is 0.5 kg/s. High pressure steam Low...
