Consider the conditions of 1.22, but the surroundings
Chapter , Problem 1.73(choose chapter or problem)
Consider the conditions of 1.22, but the surroundings temperature is 25 C and radiation exchange with the surroundings is not negligible. If the convection coefficient is 6.4 W/m2 K and the emissivity of the plate is 0.42, determine the time rate of change of the plate temperature, dT/dt, when the plate temperature is 225 C. Evaluate the heat loss by convection and the heat loss by radiation.
