Experiments have shown that, for airflow at T = 35°C and Vi = 100 m/s, the rate of heat transfer from a turbine blade of characteristic length L₁ = 0.15 m and surface temperature Ts.1 = 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 Tₛ₂ = 400°C in airflow of T = 35°C and V250 m/s? The surface area of the blade may be assumed to be directly proportional to its
