Water is boiling in a 25 cm diameter aluminum pan (k=237 W/mK) at 95 degrees C. Heat is transferred steadily to the boiling water in the pan through its .5 cm thick flat bottom at a rate of 800 W. if the inner surface temp of the bottom of the pan is 108 degrees C determine the boiling heat transfer coefficent on the inner surface of the pan and the outer surface temp of the bottom of the pan.
