Hi I'm trying to work out the following problem
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, density = 40 Kg/m3, viscosity = 11x10-6)
This is from an exam paper and at the end of the paper there's a moody diagram with roughness values, the closest to stainless steel is commercial steel and has a k value of 0.045 mm.
