In practice, the Panhandle equation is commonly used for large diameter greater than 10″ long pipelines usually measured qpi miles rather than feet where the Reynolds number is on the straight line portion of the Moody diagram, It can be seen where: Consid- should be given tothequalityand condition of the eration should be giventominimizebendsand stream at each location.

This is particularly important where stream control valve malfunction, and external two or more relief devices may relieve simultane- fire.
