The system in Fig 2 pumps water from a lower reservoir to a higher reservoir. The pipe diameter is 0.255 m and the pipe lengths are L1= 3.5 m, L2= 4 m, L3= 5 m, and L4= 0.4 m. The impeller of the centrifugal pump has a diameter of 0.4 m and operates at 950 rpm. The uniform blade height is 58 mm. The water enters the pump parallel to the pump shaft with a flow rate of 0.135 m³/s. Take viscosity as 0.00112 N s/m².

I need help on this pls

The system in Fig 2 pumps water from a lower reservoir to a higher reservoir. The
pipe diameter is 0.255 m and the pipe lengths are L1= 3.5 m, L2= 4 m, L3= 5 m,
and L4= 0.4 m. The impeller of the centrifugal pump has a diameter of 0.4 m and
operates at 950 rpm. The uniform blade height is 58 mm. The water enters the
pump parallel to the pump shaft with a flow rate of 0.135 m³/s. Take viscosity as
0.00112 N s/m².

Work to 4 significant digits. Enter all values using base units or their combinations,
i.e. m, m/s, Pa, N. Do not use multiples as e.g. mm, kPa.
You can use values with exponents, such as 0.12e3.

What would be the shaft power required to turn the impeller if the exit blade
angle is 48 degrees.
The value of the shaft power is
b)
Find the major losses in the system. Take the pipe Darcy friction factor as 0.05.
The value of the major losses is
c)
Find the minor losses in the system considering the 90 degrees elbows' losses
and the exit/entrance losses of the tanks. Consider that the exit of tank 1 is
sharp-edged and take the loss coeffcient of the entrance of tank 2 as 1.
