An object of irregular shape has a characteristic length of L1=1m with its surface maintained at a uniform temperature of Ts1=520K. When placed in atmospheric air at a temperature of T1=310K and moving with a velocity of V1=50m/s, the average heat flux from the surface to the air is q1= 15,000W/m2. A second object having the same shape, but with a characteristic length of L2=2.5m, is maintained at a surface temperature of Ts2=257C and is placed in atmospheric air at T2=27C. Is it possible, under the given conditions, to have the value of the average heat flux q2 from the surface
