Water at 75°C flows over a 2-m-long, 2-m-wide surface of a platewhose temperature is 5°C with a velocity of 3.4 m/s. Determine thetotal drag force acting on the plate in Newton (N). Properties ofwater at the film temperature of (75 + 5)/2=40°C are ν = 0.658 ×10−6 m2/s and ρ = 992 kg/m3
The total drag force acting on the plate is
