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 SAE30W oil at 20°C, with L 2 m, b 60 cm, and h = 3 cm?
