Fundamentals of Heat and Mass Transfer Seventh Edition Problem – 1.22
The free convection heat transfer coefficient on a thin hot vertical plate suspended in still air can be determined from observations of the change in plate temperature with time as it cools. Assuming the plate is isothermal and radiation exchange with its surroundings is negligible, evaluate the convection coefficient at the instant of time when the plate temperature is 225 degree C and the change in plate temperature with time (dT/dt) is -0.022 K/s. The ambient air temperature is 25 degree C and the plate measures 0.3×0.3 m with a mass of 3.75 kg and a specific heat of 2770 J/kg-K.
