Unformatted text preview: casing can be neglected, the angular velocity of the impeller obeys the equation I d dt + R 2 Q = T where I = 2 R 4 h . (b) If the impeller is stationary at t = 0, and a constant torque T is applied at t 0, obtain (t) . Sketch (t) and compare with the corresponding solution for Problem 5.20. Why is a final steady state reached in this problem, and not in Problem 5.20? ANSWER...
