Dry air at 65oC blows over a 30-cm-square plate at a velocity of 6 m/s. The plate is covered with a smooth porous material, and water is supplied to the material at 25oC. Assuming that the underside of the plate is insulated, estimate the amount of water that must be supplied to maintain the plate temperature at 38oC. Assume that the radiation temperature of the surroundings is 65oC and that the porous surface radiates as a blackbody.
