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 10 m and there are 10 window panels. a. Calculate the average convection coefficent for the 1st, 3rd, and 10th window panels when the wind speed is 5 m/s. Use a film temperature of 300K to evaluate the thermophysical properties required of the correlation. Would this be a suitable value of the film temperature for ambient air temperatures in the range of -15°C <_ T[infinity] <_ 38°C?b. For the 1st, 3rd, and 10th windows, on one graph, plot the variation of the average convection coefficients with wind speeds in the range of 5 <_ u[infinity] <_ 100 km/h. Explain the major features of each curve and their relative magnitudes.
