  • Steam & Boiler Unit Calculator - Roth Pump

    BHP = Boiler Horsepower - The boiler's capacity to deliver steam to a system. LB / HR = Pound per hour - Mass flow rate. It is particularly useful when dealing with gases or liquids, as volume flow varies more with temperature and pressure. BTU / HR = measuring energy per unit time - Equal to 1 BTU being output in an hour.Learn More
