In most industrial facilities, because of inadequate instrumentation and incomplete records, it is easier to prepare a mass balance than to prepare a heat or energy balance. A heat or energy balance is more informative. A mass balance deals only with quantity. It tells how many pounds of steam are used. A heat balance deals with quality and ...
