An aluminum plate with a thickness of 2L=0.22m is initially at a temperature of To=250°C. The plate is suddenly brought into contact with a fluid at a temperature of T∞=50°C, where the convection heat transfer coefficient is h=500 W/ m2K. Determine
a. the mid-plane temperature at t=300 seconds.
b. the total heat transfer from the plate to the fluid in 300 seconds if the surface area of one side of the plate is 1 m2 .
