1: The belt in the figure moves at steady velocity v and skims the top of a tank of oil of viscosity u. (1) Assuming a linear velocity profile, develop a formula for the belt-drive power P required as a function of (h, L, V, B, µ). Neglect air drag. (2) What power P in watts is required if the belt moves at v = 2.5 m/s over SAE 30 W oil at 20°C of µ = 0.29 kg/m•s., with L = 2 m, b = 60 cm, and h = 3 cm?
