An experiment is to be conducted to determine heat transfer coefficient on the surfaces of tomatoes that are placed in cold water at 7 [Degree Celsius]. The tomatoes (k=0.59 W/(m*K), alpha=(0.141*10^-6) m^2/s, p=999kg/m^3, Cp=3.99KJ/(kg*K)) with an initial uniform temperature of 30 [Degree Celsius] are spherical in shape with a diameter of 8cm. After a period of 2 hours, the temperatures at the center and the surface of the tomatoes to be 10.0 [Degree Celsius] and 7.1 [Degree Celsius], respectively. Using analytical one-term approximation method (not the Heisler charts), determine the heat transfer coefficient and the amount of transfer during this period if there are eight such tomatoes in water.
