A cylindrical block of aluminum of diameter of 50cm and height 5cm slides down a smooth inclined surface as shown in Fig. Determine the terminal velocity, steady speed achieved by an object freely falling through a fluid, of the block if the 0.1 mm gap between the block and the surface contains SAE 10 W oil at 20C. Assume the velocity distribution in the gap is linear. 0.1 mm gap 20°
