A flat plate, 1 m wide and 1.5 m long, is maintained at 90°C in air with a free stream temperature of 10°C flowing along one side of the plate. The thermo-physical properties of air are v = 20.92 × 10^-6 Ns/m^2, k = 0.028 W/mK, and Pr = 0.703. Determine the velocity of air if energy dissipation is 3.75 kW. Use the following correlations:
Laminar flow: Nu = 0.664Re^0.5 Pr^1/3
Mixed flow: Nu = [0.037Re^0.8 - A]Pr^1/3
