2018-8-5 · Select the line corresponding to the required flow, and the column corresponding to the nominal pipe size. The intersection will give the pressure drop in psi per 100 feet of equivalent pipe length. For example, a typical No. 2 fuel oil has a viscosity 40 SSU. A 500 hp boiler requires up to 115 gallons per hour of No. 2 oil.
