Air at a pressure of 6000 N/m^2 and temperature of 300 degrees Celsius is flowing with a velocity of 10m/s over a flat plate 0.5m long.
Estimate the cooling rate per unit width of the plate needed to maintain it a surface temperature of 25 degrees Celsius.
Consider air to be an ideal gas.
How does this cooling rate change if the velocity of the air is 100m/s?
