An electrically heated plate 15cm high and 10cm wide is maintained at 140°C. Estimate the rate of heat dissipation from both sides of the plate in an atmospheric at 20° C, if the radiation heat transfer co-efficient is 8.72W /m² -K. For air at the mean temperature of 80°C; Take kinematic viscosity= 21.09x10 m² /s, Pr 0.692, and k = 0.0305 W/m-K.
