Q2: It is required to heated Oil in a stirred tank, Oil enters the tank at a rate of 100 kg/h at 25°C and leaves at temperature T. The tank holds 2300 kg of oil, which is initially at 25°C. The heat is provided by steam condensing at 130°C in coils submerged in the tank, The rate of heat transfer is given by : Q =h(Tecum-T) The heat capacity of the oil is given by Cp = 2.1 J/(g°C) and the heat transfer coefficient is h = 115 J/s °C. neglect the shaft work of the stirrer. Once the process is started, how long does it take before the oil leaving the tank is at 30°C? bahof 25 c ( 20 Marks) Stundensing
