An 8-m-internal diameter spherical tank made of 1 5-cm-thick stainless steel (e -15w im k) is used to store iced water at o c the tank is located in a room whose temperature is 25 °c the walils of the room are also at 25 "c the outer surface of the tank is black (emissvity ? =1), and heat transfer between the outer surface of the tank and the surroundings is by convection and radiation the convection heat transfer coefficients at the inner and outer surfaces of the tank are 80 w/m2 k and 10 w/m2 k respectively determine, (a) the rate of heat transfer to the iced water in the tank and (b) the amount of ice at 0 °c that melts dunng a 24 hour perod the heat of fusion of water at atmospheric pressure is h, -333 7kjikg (22)
