Experiments have shown that, for airflow at T = 35°C and V₁ = 100 m/s, the rate of heat transfer from a tur- bine blade of characteristic length L₁= 0.15 m and sur- face temperature T1 = 300°C is q₁ = 1500 W. What would be the heat transfer rate from a second turbine blade of characteristic length L₂ = 0.3 m operating at 2= 400°C in airflow of T. = 35°C and V₂ = 50 m/s? The surface area of the blade may be assumed to be directly proportional to its characteristic length.
