Fluid Flow Systems
Isothermal pipe flows
In isothermal pipe flows, as the name implies, the temperature of the fluid is constant, i.e., the heat transfer between the fluid and the pipe walls is sufficiently high to keep the temperature of the gas and the ambient temperature the same. Typically, this approximation applies to compressible fluids that flow slowly in pipes without heat isolation, such as natural gas pipelines. Assuming constant density, i.e., incompressible case, the loss of a straight section of pipe with a constant cross-section is given by the following equation:
