A styrofoam cooler has a total area(including the lid) of 1.0m^2 and a wall thickness of 1.0 cm. It is filled with ice, water, and cans of ice-tea. They are at a temperature of 0 degrees celsius.

a) What is the rate of heat flow into the cooler if the temperature of the outside is 20 degrees celsius?

b) How much ice melts in one hour?

A plane wall has thickness of 5 cm, thermal conductivity of 2 W/mK and generates heat. The left face of the wall (x=0) has a surface temp. of 80C and has air at 20C flowing past it with a heat transfer coefficient of 50 W/m^2K. If the right face is insulated then the temperature distribution through the wall has a general format T(x)=A+B*x+C*x^2 (a) Draw a properly labeled diagram (including a representative temperature distribution), state all assumptions and calculate the...
