Question

A liquid with density 1010 kg/m³ and viscosity 1.2 mPa.s drains from a building through
a commercial steel pipe (I.D. 2.54 cm) to a pond as shown in the following Figure. The
pipe is made of three segments as shown in the following Figure.

21 m
Segment A
L-25 m
2.365
6.452
8.1072
8.956
17 m
Segment B
L-40 m
6m
Segment C
L=7 m
(P3) (P4)
Pond
The pressures are measured at points P1, P2, P3, and P4. The pressure at the inlet
(P1) is 141 kPa and Patm = 101 kPa. The speed of the liquid through Segment A is 0.40
m/s.
If water was to be pumped from the pond to the building through the pipe, what
would be the power required? (HINT: Power = Q (deltaP))
