Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Textbook Question

Chapter 10, Problem 64P

A Kaplan (propeller with variable-pitch blades) turbine with a rated capacity of 83 MW at a head of 24 m and 86 rpm was one of 14 units installed at the McNary project on the Columbia River. The characteristic runner diameter is 7 m. If a 6-m head is available in the laboratory, what should be the model scale, flow rate, and rpm?

A Kaplan turbine has the following specifications: H =25 ft., N=400 rpm; power = 650 hp. If the efficiency of the unit is 90%, estimate (a) the flow rate, (b) approxi-mate diameter of the runner, (c) turbine setting to avoid cavitation if the location is at sea level, and (d) turbine setting to avoid cavitation if the location of the unitis at an elevation of 5000 ft. The local temperature is 60°F.Ans: (a) Q=254 cfs; (c) Hs=5.8 ft.; (d) 0.12 ft.

For a high-fl ow site with a head of 45 ft, it is desired to designa single 7-ft-diameter turbine that develops 4000 bhp at aspeed of 360 r/min and 88-percent effi ciency. It is decidedfi rst to test a geometrically similar model of diameter 1 ft,running at 1180 r/min. (a) What likely type of turbine is inthe prototype? What are the appropriate (b) head and(c) fl ow rate for the model test? (d ) Estimate the powerexpected to be delivered by the model turbine.

At a hydraulic plant the propeller type turbine are rated at 48,000 HP at 82 rpm under a 14 meters head, the diameter is 7 meters, for a geometrical similar turbine to develop 36,000 HP under a 11 meters head. After resolving the percentage change in probable flow, determine the following: (A) What diameter, in meter, of the impeller to be used? (B) What is the speed, in RPM, should be used?
