How Is Steam Flow Rate Calculated From Boiler

General Engineering Data - Cleaver-Brooks

2018-8-5 · Figure 2 allows pressure drop in psi or ft. of water to be calculated for a given flow and pipe size. Like Figure 1, working backwards will allow pipe size to be calculated for a target pressure drop. This figure will work with either water flow in a hot water system boiler or feedwater to a steam boiler. This assumes a constant
