Natural Gas Pipeline Flow Calculations
Credits: 3 PDH
PDH Course Description:
Several different equations have been proposed and are in use for natural gas pipeline flow calculations. This course provides information about four of them, the Weymouth Equation, the Panhandle A Equation, the Panhandle B Equation, and the Darcy Weisbach Equation, along with information about the fluid properties needed and their estimation or calculation.Topics:
At the conclusion of this course, the student will:- Be familiar with the natural gas properties, density, specific gravity, molecular weight, compressibility factor, and viscosity, and their use in pipeline flow calculations.
- Be able to calculate the compressibility factor for natural gas with specified average gas pressure and temperature and known specific gravity.
- Be able to calculate the viscosity of natural gas with specified average gas pressure and temperature and known specific gravity.
- Be able to obtain a value for the friction factor using the Moody diagram for given Re and /D.
- Be able to calculate a value for the friction factor for specified Re and /D, using the appropriate equation for f.
- Be familiar with the guidelines for when it is appropriate to use the Darcy Weisbach equation for natural gas pipeline flow calculations.
- Be able to use the Darcy Weisbach equation and the Moody friction factor equations to calculate the frictional pressure drop for a given flow rate of a specified fluid through a pipe with known diameter, length and roughness.
- Be able to use the Weymouth equation to calculate gas flow rate through a pipe with known diameter and length, elevation difference between pipeline inlet and outlet, specified inlet and outlet pressure and enough information to calculate gas properties.
- Be able to use the Panhandle A equation to calculate gas flow rate through a pipe with known diameter and length, elevation difference between pipeline inlet and outlet, specified inlet and outlet pressure and enough information to calculate gas properties.
- Be able to use the Panhandle B equation to calculate gas flow rate through a pipe with known diameter and length, elevation difference between pipeline inlet and outlet, specified inlet and outlet pressure and enough information to calculate gas properties.
