Question
Air with free stream temperature of 10 C is flowing over a flat plate
(1.5m long and Im wide). The air is flowing along 1.5m side of the plate.
The plate is maintained at 90 C. Find the velocity of air required to have
a rate of heat dissipation as 3.75 kW. Use the correlations:
Nu =0.664Res Pro3 for laminar flow
Nu, = (0.037R *-871)Pr for turbulent flow
Take the properties p = 1.0877 kg/m u=2.029x10 m/s, k=0.028
W/mK, C,-1.007KJ/kg.K and Pr=0.703
