Question

An actual aircraft is cruising at -55.4°C, 18.8 kPa and 900 km/h. A heating system keeps the wings just above freezing temperatures of 0°C. Should the wing diameter evaluated as D = 0.5m, the following are to be determined: (i) Estimate the suitable Nusselt number for this situation, (ii) Compute the average convection heat transfer coefficient on the wing surface, and; (iii) Evaluate the average rate of heat transfer per unit surface area.
