A frustum-shaped body is rotating at a constant angular speed of 200 rad/s in a container filled with SAE 10W oil at 20°C (Î¼ = 0.100 Paˆ™s), as shown in Fig. P10€“32. If the thickness of the oil film on all sides is 1.2 mm, determine the power required to maintain this motion. Also determine the reduction in the required power input when the oil temperature rises to 80°C (Î¼ = 0.0078 Paˆ™s).

Case SAE 10W oil D= 12 cm L = 12 cm d=4 cm
