Question
A perfectly stirred cylindrical tank (D =zm, H = 1.6 m) with steam jacket, is initially full of a milk [p=1080 kg/m, C3.9 ky/kg.C,
T(0)=5°C] The steam jacket surrounds the sides of the tank only. Steam, enters and leaves the jacket at the same termperature
(Ts=115 °C). The top and the bottom of the tank are completely insulated. The overall heat transfer coefficient from the steam to
the milk is U-640 W/m? °C. How long will it take, in minutes, for the milk to reach 75 C?
