Example 4: Temperature Change in a CSTR Water Inlet Q: 60kW (25°C) Та (10°C) Water Outlet (T) • A CSTR with a lateral area of 4m² and an overall heat transfer coefficient of 100W/m2.°C containing 100 kg of pure water at 25°C is fed by water at 25°C with a flow rate of 1 kg/s. If the power of the heater is 60kW and the ambient temperature is 10°C: a) what will be the temperature of the water in the tank after 5 minutes? b) what is the maximum temperature that can be reached? (c=4180 J/kg. °C) . • Assume perfect mixing • Assume c is constant Assume mass inlet and outlet are equal.
