To determine the average convection heat transfer coef-
ficient for a representative operating condition, an
experiment is performed in which the coated blade is
exposed for 30 min to atmospheric air at the desired
velocity and a temperature of T = 27°C. During the
experiment the surface temperature is T. = 27°C, and at
its conclusion the mass of the blade is reduced by
Am = 8 g. What is the average convection heat transfer
coefficient associated with the operating condition?
