Question:-A cylindrical steel tank with a diameter of 3 m and height of 4.4 m is used to store chilled water (at 9.3 °C) as part of an air conditioning system for a building. The heat transfer (convection) co-efficient for the surface of the tank in contact with the water in this application is 15 W/(m2.K).Given the surface temperature of the metal tank is 40 °C.At what rate must heat energy be removed from the water just to maintain its temperature constant at 9.3 °C ?Assume the tank is an enclosed cylinder and that the tank is always full. Note - the thickness of the tank is not relevant to this problem. Work in base SI units.

Given: r = d/2 = 3/2 = 1.5 m H = 4.4 m h = 15 W/m2K

Question:-

A cylindrical steel tank with a diameter of 3 m and height of 4.4 m is used to store chilled water (at 9.3 °C) as part of an air conditioning system for a building. The heat transfer (convection) co-efficient for the surface of the tank in contact with the water in this application is 15 W/(m².K).

Given the surface temperature of the metal tank is 40 °C.

At what rate must heat energy be removed from the water just to maintain its temperature constant at 9.3 °C ?

Assume the tank is an enclosed cylinder and that the tank is always full. Note - the thickness of the tank is not relevant to this problem. Work in base SI units.
