Evaluate the temperature gradient in the flow direction, Mechanical Engineering

Assignment Help:

A plane wall (thermal conductivity = 10.2 w/moc) of 100 mm thickness and area 3m2 has steady surface temperature of 170oc and 100oc.

Evaluate :-

(i) The temperature gradient in the flow direction.

(ii)The ratio of flow of heat across the plane wall.

(b) Calculate the heat transfer by convection over a surface of 0.75m2 if the surface is at 200oc and the fluid is at 80oc. The value of convective heat transfer co-efficient is 25 w/m2 oc.
