Consider the stirred tank heating process shown in the following figure T т 0 Q Heater The volume of the water, Vin the tank is constant equal to 500 liters, and the mass flow rate of water in and out, w, is constant equal to 100 kg/min. Following properties of liquid water may be assumed constant density p=996 kg/m3 specific heat C = 4.18 kJ/kg K Initially , the process is operating at steady state with Tiss = 20 °C and 0 ss = 15000 kJimin. (a) Calculate the initial steady state temperature Tss in degrees Celsius (b) At time=0, heat input rate Q is suddenly decreased by 5000 kJ/min Calculate outlet temperature T (in degrees Celsius) after 5 minutes
