The performance data of a water pump follow the curve fit Havailable = H0 − aV.2 , where the pump’s shutoff head H0 = 7.46 m, coefficient a = 0.0453 m/(Lpm)2 , the units of pump head H are meters, and the units of V. are liters per minute (Lpm). The pump is used to pump water from one large reservoir to another large reservoir at a higher elevation. The free surfaces of both reservoirs are exposed to atmospheric pressure. The system curve simplifies to Hrequired = (z2 − z1) + bV.2 , where elevation difference z2 − z1 = 3.52 m, and coefficient b = 0.0261 m/(Lpm)2 . Calculate the operating point of the pump (V.operating and Hoperating) in appropriate units (Lpm and meters, respectively).
1Two water pumps are arranged in series. The performance data for both pumps follow the parabolic curve fit Havailable =H0 =aV ^2. For pump 1, H0 =5.30 m and coefficient a =0.0438 m/Lpm^2; for pump 2, H0 =8.70 m and coefficient a =0.0347 m/Lpm^2. In either case, the units ofnet pump head H are m, and the units of capacity V are Lpm.Calculate the combined shutoff head. Complete Answer, thank you
The performance data of a water pump follow the curve fit Havailable = H0 = aV^2, where the pump’s shut off head H0=5.30 m, coefficient a =0.0453 m/(Lpm)^2, the units of pump head H are meters, and the units of V. are liters per minute (Lpm). The pump is used to pump water from one large reservoir to another large reservoir at a higher elevation. The free surfaces of both reservoirs are exposed to atmospheric pressure. The system curve simplifies to Hrequired =(z2- z1) + bV ^2, where elevation difference z2 =-z1 = 3.52 m,and coefficient b =0.0261 m(Lpm)^2. Calculate the operating point of the pump.

Vacumm You are designing a vacuum system with a desired equilibrium pressure of 10-7 torr. The turbomolecular pump you are using has a pumping speed of 400 L/s. What is the maximium surface area of the chamber that you can allow, assuming that the outgassing rate per square cm 10-9 torr L/s? Note : total outgassing rate G = ( outgassing rate per area ) * ( area )
A Pelton wheel operates from an effective head of He = 450 m and at a flow rate of 5.0 m³/s. The wheel radius is r2= 0.85 m and its rotational speed is 430 rpm. The water which leaves the penstock is divided into a few streams. The nozzle coefficient is CN = 0.98 for each of the nozzles. Impulse blades turn the flow into the direction ß3 =-62° and as a result of friction the relative velocity reduces by an amount which gives a velocity coefficient cv = 0.96. Find, (a) the efficiency of the turbine, (b) the power specific speed, (c) the jet number, d) the nozzle diameter e) the number of buckets in the wheel. First find the exit velocity from the nozzle and the blade speed; V2 = CN V29H.
