Underground water needs to be pumped into a pool
The school decides to create a new Fluids test facility on the lab building roof. Underground water needs to be pumped bu a 7373% efficient 5.05.0-kW submerged pump to the facility, which has a free surface h=3030 m above the underground water level. The diameter of the pipe is 7.07.0 cm on the intake side and 5.05.0 cm on the discharge side.Assume the elevation difference between the pump inlet and the outlet and the effect of the kinetic energy correction factors to be negligible.a) Determine the maximum...

3. Water flows steadily through a curved duct that turns the flow through angle 0= 135º, as shown in Fig. 3. The cross-sectional area of the duct changes from Aj 0.025 m² at the inlet to A2 = 0.05 m² at the outlet. The average velocity at the duct inlet is V1 = 6 m/s. The momentum flux correction factor may be taken as Bi= 1.01 at the duct inlet and B2 = 1.03 at the...

1. Water is pumped from a low reservoir to a high reservoir that is 20 m higher in elevation. The water is flowing at 1.5 m/s through a 305 mm internal diameter piping system. The water is at 18 degrees C. There are 1,000 m of piping, six standard 45 degree bends, two standard 90 degree bends, a branch flow tee, three gate valves, a swing check valve, a square inlet and a square outlet. The piping and valves are...
