CT00AA32-3008 Heat ... Kysymys 2/4 - Yleiskatsaus Suunnitelmat What is the needed steam mass flow rate? Resurssit Task 2. Energy and mass balance A liquid solution stream is continuously heated in a jacketed reactor with a net heat flow rate of 86 kJ/s. The mass flow of the solution is 0.4 kg/s. The inlet temperature of the solution is to 18 C and the mean specific heat is 3.94 kJ/(kg-K). The pressure of the solution side is 1.1 bar. The heating is carried out with 135 C superheated steam at a pressure of 2.2 bar produced by an electric steam generator. The steam exits the jacketed reactor slightly subsaturated at a temperature of 105 C. W Tila ja seuranta The reactor is rather poorly insulted, and the outer most surface temperature of the tank heats up to a temperature of 68 C. The area of the outer most surface is 3.8 m2, and the mean convective heat transfer coefficient is approximated to be 18 W/(m2-K). The room air temperature is 19 C. The steam generator can be considered to
