Consider weather conditions for which the prevailing wind blows past the penthouse tower on a tall building. The tower length in the wind direction is 10m and there are 10 window panels.

(a) Calculate the average convection coefficient for the first, third, and tenth window panels when the wind speed is 5 m/s. Use a film temperature of 300 K to evaluate the thermo physical properties required of the correlation, would this be a suitable value of the film temperature for ambient air temperatures in the range 15 (b) For the first, third, and tenth windows, on one graph, plot the variation of the average convection coefficient with wind speed for the range 5
