Oil, depth h
The belt in Fig. P1.52 moves at a steady velocity V and
skims the top of a tank of oil of viscosity μ, as shown.
Assuming a linear velocity profile in the oil, develop a
simple formula for the required belt-drive power P as a
function of (h, L, V, b, µ). What belt-drive power P, in
watts, is required if the belt moves at 2.5 m/s over SAE
30W oil at 20°C, with L = 2 m, b = 60 cm, and h = 3 cm?
