if the length of a pipe doubled what will be the effect on
Pressure in line?

Answer Posted / baskar

If it is a gas then the pressure will reduce to half .Use
the below gas equation,

p1/p2 = v1/v2

If it is an incompressible fluid,also the pressure gets
reduced.Then the major loss of energy in pipe is caused by
friction in pipe.It may be computed by Darcy-weisbach
equation.

Head loss due to friction hf = 4fLV2/2gD

where,
f= friction factor
L=length of pipe
v=velocity of the fluid
D=diameter of the pipe

If L is doubled obviously friction increases and therfore
the pressure is reduced.
