Aglass tube 1 m long, 2mm thick with 20mm outside diameter is filled with water at foc. The convective heat transfer Coefficient between the water and inside. surface of the tube is 200 W/m²- c). The ambient temperature is yo ĉ and the heat transfer coefficient on the outside of the tube is 25 W/m². c Neglecting the heat loss from the tube ends Calculate the time required for the water to reach atemperature of 20c, find the equilibrium temperature.
