Q2) Design a Francis turbine with the following specifications: Head available 68m Speed Power output Hydraulic efficiency Overall efficiency Flow ratio X 750 rpm 330kw 94% 85% 0. 15 0.1 Breadth to diameter ratio at inlet Outer to inner diameter ratio 1/2 Assume 6% of circumferential area of runner occupied by thickness of vanes and flow velocity remains constant and flow is radial at exit.

Considering the wind speed of 5 m/s, air density of 1 kg/m3, exponentfactor is 0.20 and turbine diameter of 100 m:a. Calculate the turbine electrical power considering the maximumBitz limit,b. The original wind speed was taken at a height of 10 m,calculate the turbine power if it is now installed at 50 m height.c. In what condition a capacity factor of 73% can be reached bythis turbine.

Please solve question four

Analyze to select the type of the turbine when its diameter is 600 mm, rotational speed is 600 rpm and working under a water head of 120 meters. The buckets deflect the 100 mm diameter jet through an angle of 165°. Take the coefficient of velocity for the nozzle as 0.97. Use Table given below for selection of turbine. Sr. # Specific speed (rpm) Type of turbine 1 8-30 Pelton wheel with one nozzle 30 - 50 Pelton wheel with 2 or more nozzles 50-250 Francis turbine 4 250-1000 Kaplan turbine 2. 3.

I juest need help with part b. As you can see 22.9 is incorrect. I will rate your answer, thanks!

Problem-3: A centrifugal pump lifts water against a static head Az = EN m. The pipe setup has a constant diameter of 0.08 m, major losses in the suction side h, = EN3 m and in the discharge side hLD is 3 m. The pump impeller has a diameter of 0.15 m, exit width of 0.015 m, exit blade angle of 22° and speed of N = 20EN rpm. The hydraulic efficiency is 0.85. If the flow at the entrance is radial, find the discharge, pump head, atmospheric pressure Pat, Vapor pressure P, and maximum allowable height of the pump from the feeding tank water surface elevation if the pump is operating under T 25 °C at altitude H= 20EN m. %3D 0, = NPSHR/Hp =1.21×10³N = (P EN=62 Is-mx at-abs-P,)/Y-hLsT -0H, Pa-abs /Y = 10.33(1– 2.256x10-H)56 P,ly = e14.29-3985(T+233.4))
