All units are in g/hp-hr and shown at 100% load (not comparable to EPA weighted cycle values). Emission levels of the engine may vary with ambient temperature, barometric pressure, humidity, fuel type and quality, installation parameters, measuring instrumentation, etc. The data was obtained in compliance with US EPA regulations. A hour containing 3600 seconds. 1 Kilogram per hour = 1 / 3600 kilograms per second (SI base unit). 1 kg/h ? 0.000 277 778 kg/s. 1 Pound per Minute: Mass flow of pounds across a threshold per unit time of a minute. Let's calculate the mass flow of air when a value of 1000 SCFM (Standard Cubic Feet per Minute) is used. To determine the operating parameters, standard conditions must be provided. The most common standard conditions for air is the CAGI or ASME standard which is 14.7 psia (pressure), 68°F and 36% Relative Humidity.Oct 23, 2020 · Given a variable speed centrifugal pump initially pumping 32,000 pounds per hour(lbm/hr) at a discharge pressure of 35 pounds per square inch, gauge (psig), calculate the final stable discharge pressure after the pump speed is raised by 50%
