An oil of relative density `0.9` and viscosity `0.12 kg//ms` flows through a `2.5 cm` diameter pipe with a pressure drop of `38.4 kN//m^(2)` in a length of `30 m`. Determine
Determine the power required to maintain the flow

A

2.2 W

B

3.84 W

C

5.6 W

D

9.3 W

Text Solution

Verified by Experts

The correct Answer is:
B

We know that ` P = FV = (P _ 1 - P _2 ) AV = (P _ 1 - P _ 2 ) Q rArr P = (38.4 xx 10 ^(3)) (1 xx 10 ^(-4)) ` or P = 3.84 W
