QI): Impulse turbine diameter 3.2m O = 0: Angular velocity = 25 rad/s Absolute velocities V, 140m/s and V; = 110m/s Power developed by the wheel = 300kw Calculate: 1. the blade velocity. 2. the force exerted and Jet 25mmd 3. the angle 0. Q2): Consider flow of an incompressible fluid of density p and viscosity u through a long, horizontal section of round pipe of diameter D. The velocity profile is V. A surface tension a. Develop a non-dimensional relationship between surface tension o and the other parameters in the problem. Q3): When crude oil (r.d = 0.855, u = 71.8 10 Pa. s) flows in a 50 mm horizontal pipeline at 4.5 m/s, a pressure drops of 6500 kPa occurs in 60 m of pipe. Calculate the pressure drop in the coresponding length of a pipe model 25 mmd when gasoline (r.d = 0.68,p = 2.9*10 Pa. s) flows in the model for complete similarity between model and prototype.
