Steam at 150 bars and 600 oC passes through process equipment and emerges at 100 bars and 700 oC. There is no flow of work into or out of the equipment, but heat is transferred. Using the steam tables, compute the flow of heat into the process equipment per kg of steam b.) Compute the value of enthalpy at the inlet conditions, Hin, relative to an ideal gas at the same temperature, Hig. Consider steam at 1 bar and 600...

Please help me solve this correctly. Show all work. Thanks! Saturated steam at a gauge pressure of 5.00 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 795 m3/min and is heated at constant pressure to 93°C. The steam condenses and leaves the exchanger as a liquid at 27.0°C. Please help solve this correctly. Please show work. Thanks! The specific enthalpy...
