How to Convert Steam Flow to Megawatts | Sciencing

Steam flow is typically measured in pounds per hour (lb/hr). Steam has a measure of heat that is given in British Thermal Units (Btu) per pound of steam. The heat in steam is also a function of the temperature and pressure of the steam. If the steam flow is known and the duration of flow is also known, then the steam

In the following equations, the operating cost of the boiler is CO per hour and the process requires S pounds/hour (lb/h) of steam. To deliver this much steam, it is necessary to actually generate (1+X)S lb/h of steam, where X is a factor typically ranging from 5 to 20%. So we already have two distinct equations to determine the cost of steam:
