Methane enters a heat exchanger at a volumetric flow rate of 135.0 m³/min, at an absolute pressure of 1.013 bar and temperature of 5.0 °C. At these conditions, the specific enthalpy of methane is -45.181 kJ/kg. The methane leaves the heat exchanger at an absolute pressure of 1.013 bar and temperature of 75.0 °C. The corresponding specific enthalpy at these conditions is 113.783 kJ/kg. The methane is heated by a stream of saturated steam entering the heat exchanger at 2.2 bar (absolute) and leaving as a liquid at 52 °C. Find the volumetric flow rate of saturated steam into the heat exchanger by following the steps. What is the mass flow rate of methane into the heat exchanger? mass flow rate: What rate of heat is supplied to the methane stream in order to heat it from 5.0 °C to 75.0 °C? rate of heat: What is the minimum mass flow rate of saturated steam into the heat exchanger? mass flow rate: What is the volui X10 TOOLS volumetric flow rate: team into the heat exchanger? kg methane/min KW kg saturated steam/min m³ saturated steam/min
