Please answer question 7:
A centrifugal pump discharges 500 GPM through a 12-inch diameter
impeller. The fluid leaves the impeller with a
tangential velocity of 17 ft/sec. If water, @ 68°F,
enters the impeller via radial flow (I.E. no whirl), and the inner
radius and thickness of the impeller are
1.75-inches. (Assume a constant thickness of the
impeller) and if the pump speed is 1775 rpm, with a head loss of
4.5-feet. What is the horsepower input to the flow by
the pump?

Q2: A centrifugal pump with an impeller diameter of 220 mm has to pump 0.02 mº/s of brackish water to an RO unit with following performance data at the best efficiency point: impeller speed =3000 rpm, total head= 68 m, net positive suction head=1.8 m, input power=16 hp. Evaluate the performance of a homologous pump with twice the impeller diameter operating at half the impeller speed. (15 Marks) 2016)

You have been asked to design a similar pump from the
existing one. The existing pump works for water is of impeller
diameter equals 6 cm and its performance data is shown here when
working at 1725 rpm. The newly design pump is for a refrigerant
(R-134A) and it must produce 450 cm of head at 1600 rpm when
working at its best efficiency. One of your colleagues did
preliminary analysis and develop the performance curves in
dimensionless form for...

3. The manufacturers rating for a centrifugal pump shows that the pump delivers 160 gpm at 80 ft of head when the pump speed is 3000 rpm. This rating is for the best operating point of the pump: the efficiency at this point is 59 percent. (be careful with units) (a) Calculate the specific speed of the pump. (b) What is the horsepower required to operate the pump at the manufacturers rating? (c) A 1.8 horsepower motor with a speed...

A centrifugal pump with a 700 mm diameter rotor runs at 1800 rpm. The water enters without whirl (Q1 = 90°) and a2 = 60 (a is the angle between the absolute velocity and the local tangent to the circumference). The outlet (absolute) velocity magnitude is 6 m/s. The local gravitational field is 9.81 m/s². (a) From the Euler formula, calculate the theoretical head produced by the pump (20%), (b) if the actual head measured is 17 m, calculate the...
