Question: The total error is dominated by the 8% error in the estimate of clearance, (Ro Ri). We might state the experimental result for viscosity as

The total error is dominated by the 8% error in the estimate of clearance, (Ro €“ Ri). We might state the experimental result for viscosity as the belt in Fig. P1.52 moves at steady velocity V and skims the top of a tank of oil of viscosity μ.
Assuming a linear velocity profile, develop a simple formula for the beltdrive power P required as a function of (h, L, V, B, μ). Neglect air drag. What 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?

The total error is dominated

moving belt, width b Oil, depth h
