A) Consider a 1-m x 1.6-m horizontal plate in a room at 20oC. Its top surface is insulated, while the bottom surface is maintained at a temperature of 80oC. Determine the rate of heat transfer from the plate by natural convection.
A) Consider a 1-m x 1.6-m horizontal plate in a room at 20oC. Its top surface is insulated, while the bottom surface is maintained at a temperature of 80oC. Determine the rate of heat transfer from the plate by natural convection.
Solution
We know that heat transfer by natural convection Q = hA(T2-T1)
here A = 1.6 m2
T2 - T1 = 60oC
h = 100 W/m2 K
Q = 100*1.6*60
Q = 9.6 kJ
