A heat exchanger is used to transfer heat from a steam stream to a chlorine gas stream. 100 kg of steam at 1 bar and 200 °C enters the heat exchanger and leaves the exchanger as saturated steam at 1 bar. Chlorine gas enters the exchanger at 1 bar and 48.0 °C and leaves the exchanger at 141.0 °C. Assume the heat exchanger is adiabatic. What is the specific enthalpy of the inlet steam stream? (Use liquid water at 0.01 °C as a reference state.) Ĥ și= kJ/kg What is the specific enthalpy of the outlet steam stream? (Use the same reference state.) 50= kJ/kg What is the specific enthalpy of the inlet chlorine gas stream? (Use chlorine gas at 1 bar and 48.0 °C as a reference state.) Ĥci= kJ/mol What is the specific enthalpy of the outlet chlorine gas stream? (Use chlorine gas at 1 bar and 48.0 °C as a reference state.) ÊĤ co= kJ/mol How many moles of chlorine gas enter the heat exchanger? nc = mol What is the ratio of the volume of inlet steam to the volume of inlet chlorine gas?
