n inward flow radial turbine (see Fig. P5.140) involves a nozzle angle, a1, of 60° and an inlet rotor tip speed, U1, of 30 ft/s. The ratio of rotor inlet to outlet diameters is 2.0. The radial component of velocity remains constant at 20 ft/s through the rotor, and the flow leaving the rotor at section (2) is without angular momentum. If the flowing fluid is water and the stagnation pressure drop across the rotor is 16 psi, determine the loss of available energy across the rotor and the hydraulic efficiency involved.
Can someone help me solve problem 181, chapter 12 from Engineering Mechanics statics and dynamics, 13th edition. The question is, simply, r = 4sin(2theta), theta = (3t^(3/2))rad. Determine the velocity and acceleration when theta = 60 degrees.
