Question
1.Compute the thickness ofthe ice layer under the conditions that are given
2. Find the heat transfer rate per unit length of the pip?
This problem measures ABET Outcome (a) Water flows in a pipe of 110 mm diameter whose walls are thin enough to have no thermal resistance. When the surface temperature of the pipe reaches -17 degree C ice forms on the inner surface of the cylinder wall. Compute the thickness of the ice layer under the conditions that the water average temperature in the pipe is 2 degree C and the inside film heat transfer coefficient is 1800 W/(m2 . degree C). Assume the inner surface of the ice to be at 0 degree C. What is the heat transfer rate per unit length of the pipe? The average thermal conductivity of the ice layer is 1.943 W/(m. degree C).
