Question:

Engine oil at 105°C flows over the surface of a flat plate whose temperature is 15°C with a velocity of 1.5 m/s. The local drag force per unit surface area 0.8 m from the leading edge of the plate is
(a) 21.8 N/m²

(b) 14.3 N/m²

(d) 8.5 N/m²

(e) 5.5 N/m²
(For oil, use v = 8.565 × 10^-5 m²/s, ρ = 864 kg/m³)
