Question

A pipe line 10km long delivers a power of 50kw at its

outlet end. The pressure is 4500kN/m² at inlet and

pressure drop per km of the pipe is 50 kN/m². Assuming

F=0.025. Determine the diameter of the pipe and the

efficiency of transmission​

Answer 2

Answer:21mm

Explanation:

Given data:

L= 10km = 10000m

Power, P=50kW= 50000W

Pressure at inlet, p, = 5000kN/m

Pressure drop per km of pipeline = 50kN/mn

solution:

Pressure drop for 10km pipeline, Ap = 50x10 = 500 kN/m

Equivalent head loss, h, =.

500 50.96m
