Air at a temperature of To = 30°C and 6 kPa pressure flows with a velocity of 10 m/s over a flat plate 0.5 m long. Estimate the heat transferred per unit width of the plate needed to maintain its surface at a temperature of Ts = 45°C.
Tip: Don't forget to account for the pressure. Also, don't forget that viscosity will always be smaller than 1.
