Question

A constant heat flux of 500 W/m2 is supplied to one face of a food material (k = 1.5 W/m-K) having a plate like structure with a thickness of 10mm. From the other face of the food material, heat is dissipated by convection into a fluid at 40°C temperature. The heat transfer coefficient of the fluid is 100 W/m2.K. The temperature in °C of the food surface to which the heat flux is supplied will be

Solution

The correct option is D 48.3°C
k = 1.5 W/m.K
L = 0.01 m

T=40C

q=500W/m2

h=100W/m2.K

Heat flux =TTLk+1h500=T400.011.5+1100

T=48.33C
