The tank is insulated and therefore the energy balance over the system is governed by: dT(t) UA(Tn - T(t)) = mCp- dt = Answer the following questions: (a) Use Laplace transform to find T(t) with an initial condition of T(O) = 0 °C in terms of the variables given in this problem. (17 marks) (b) How long does it take for 500 kg of liquid from 0 °C to reach 55 °C if hot water at 90 °C circulates around the tank? The heat surface area (A) and overall heat transfer coefficient (U) are 20 m2 and 1.7 kWm-2K-1, respectively (Cp = 0.7 kJkg-1K-1).
