The pressure at the start of a 180Km stainless steel natural gas pipeline is 4MPa and at the end is 2MPa. If the diameter of the pipe is 0.4m, what will be the gas flow rate through the system? (ignore losses other than friction)

(For natural gas, ρ = 40 kg/m^3, μ = 11x10^-6 Pas).

2. Relevant equations

u = q/a

re = (u)(d)/v

hf = p/(density)(g)(Q)

3. The attempt at a solution.

Kinematic velocity; \nu=11x10-6/40 = 2.75*10-7

Reynolds number equation; Re = 1x10-6*0.4/2.75*10-7 = 16

Re number < 2100 => flow is laminar

From Moody's diagram, Friction Factor value = 0.002
