a pelton wheel is supplied with water from a reservoir situated 270m above the nozzle of the wheel . The frictional head loss in the pipe is 24m of water and the coefficient of velocity of the nozzle is .92. The output power of the pelton wheel is 2600KW when running at 659rpm. The hydraulic efficiency of the wheel is 92%.The water velocity over the blades is reduced by 10% due to friction. The supply pipe from the reservoir has a diameterof 700mm and is 596m long with f=0.01. Calculate 1) the diameter of the wheel;2)the diameter of the jet 3. the deflection angle of the buckets 4. the overall efficiency of the turbine and 5. the mechanical efficiency of the wheel.

Air is supplied to a convergent–divergent nozzle from a reservoir where the pressure is 100 kPa. The air is then discharged through a short pipe into another reservoir where the pressure can be varied. The cross-sectional area of the pipe is twice the area of the throat of the nozzle. Friction and heat transfer may be neglected throughout the flow. If the discharge pipe has constant cross-sectional area, determine the range of static pressure in the pipe for which a...

A Pelton wheel is a turbine that is the main component of a hydroelectric power plant. A Pelton wheel is made of a series of buckets arranged in a circular disk as shown in the figure below. A water jet is shot at the buckets and after striking those buckets emerges out at an angle with respect to the initial jet. A hydroelectric power plant is to be constructed in which water drops from a lake located at an elevation...

Air is supplied to a convergent–divergent nozzle from a large tank in which the pressure and temperature are kept at 700 kPa and 40°C, respectively. If the nozzle has an exit area that is 1.6 times the throat area and if a normal shock occurs in the nozzle at a section where the area is 1.2 times the throat area, find the pressure, temperature, and Mach number at the nozzle exit. Assume one-dimensional, isentropic flow.
