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.
