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
