02: 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(Tstean 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? 100 kg/h of oil enters the tank at 25 °C ( 20 Marks) in kg/h of oil leaves the tank T=? Steam condensing at 2.7 atm (130°C) in coils submerged in the tank Oil tank
