Question about Forced Convection: Flow over Flat Plates
Q: Hot engine oil flows over a flat plate. The total drag force and rate of heat transfer per unit width of the plate are to be determined.
The properties of engine ail at the film temperature of(Ts+T∞)/2=(80+30)/2=55°C=328K
Ρ=867 kg/m3
ν=123*10^-6 m2/s
k=0.141 W/m C
Pr=1505
