The Colebrook-White equation is generally valid for liquids as well as for gases, and this article shows in a simple manner how it can be used to calculate pressure losses in liquid pipelines. A program has been developed for the Texas Instruments TI-59 calculator, and the input to the program comprises: pipe data: diameter, length, roughness, elevation, and head loss coefficients; liquid data: viscosity and density; and flow data: maximum and required flow step between calculations (..delta..Q). The program then calculates the pressure loss and liquid velocity for different flows starting with O. After each calculation the flow is increased by ..delta..Q until maximum flow has been reached.
