Estimate the air flow velocity , Mechanical Engineering

Assignment Help:

A smooth glass plate is coated with a special electrically conductive film that may be used to produce a constant heat flux on the plate. Estimate the air flow velocity which must be used to remove 850 W from a 0.5-m-square plate, maintained at an average temperature of 65 0C and dissipating heat to air at 1 atm and 20 0C. Suppose the plate also radiated like black surface to the surrounding 20 0C. what flow velocity would be necessary to dissipate the 850 W under these condition.
