Just FYI, the guys at Crane responded to my question and said the isothermal equation or modified Darcy equation will give me the most accurate results.
I did ask him about breaking the pipe up into sections and using the Darcy equation, as BigInch suggested. I'll let you know what the answer is.
Thank you all for the responses!
A little more detail may clarify the use of a 2" line. The line is a hose. As it turns out, it is difficult to find hoses rated for natural gas (other than CNG which is only available up to 3/4" or so). The 2" hose is the largest available - without giong to...
The supply is for a bank of natural gas engines. I would cry if my house used that much natural gas.. The bill would be outrageus [surprise]
Section 4 is about measuring flow with differential pressure meters..
After re-reading the "Principles of Compressible Flow in Pipe" section I think...
Hello,
I'm not a fluids guy... but I need to determe the pressure drop of a natural gas supply line.
The line size is fixed - 2 inches. I'm trying to flow 47,100 ft^3/hr (1,2627 lb/hr) with an inlet pressure of 94.7 psia.
After a few calcs the mach number at the inlet is .411.
I'm a little...
