At high altitude air temperature is low and ice formation on wings can cause serious issues for air crafts.
A solution to this problem is to install heating elements within the wings. An aircraft is cruising at a
speed of 120 m/s at an altitude around 12,000 ft where air temperature is -8°C and pressure is 65 kPa.
For safety, the surface temperature of the wing is to be maintained at 8°C. The characteristic length of
the wing is 2.1 m. The area of the wing is 2.1 m by 6 m. Previous measurements showed that the average
friction coefficient between the wing and air at this condition is 0.002. You can assume the air flow to be
turbulent throughout. Determine the average heat flux that the heater must be able to supply for safe
