Programmable calculator finds gas-pipeline pressures with Colebrook-White equation
This paper presents a calculator and program for computing the pressure of natural gas pipelines. If the values of relative density of the gas, the average gas temperature, and the pipe roughness are known, the program is able to handle a system comprising 10 pipe sections of different diameters, lengths, and offtakes. The program is designed for the TI-59 calculator. It calculates either from the upstream or downstream end of the system and presents results in a printout listing for the station number, the pressure, and the offtake for each node. For each pipe section, it lists the volume flow, the length, and the pipe diameter. Offtakes are defined as positive when gas leaves the system and as negative when gas enters the system. The program can be used purely for the calculation of pressure, but the results may also be used as initial data for transient calculations where precise input may save considerable amounts of computer time.
