How to Calculate Saturated Steam Flows

The ability to calculate saturated steam flow is of utmost importance to most industrial plants that utilize steam to provide heat, ventilation and air conditioning and, in some, as an additive in the production line. Saturated steam occurs at the point at which the last amount of water in the system converts to steam. It can serve the purpose of releasing heat, resulting in a system composed of steam and some condensed water. When heat is added to the system containing saturated steam, the system becomes superheated. The calculation of a system's steam flow depends on a number of factors, but the simplest calculation method uses the system's power load.

Calculator (optional)

Instructions

- 1
  Determine the load in kilowatts (kW) that the system provides. The designs of most power plants provide enough power for the operation of an industrial plant. This includes not only heat and cooling but steam used for electrical generation and as an additive in the production line.
- 2
  Determine the working pressure of the system. This pressure determines the specific enthalpy of evaporation of steam. The enthalpy of evaporation depends on both the pressure and temperature of the system.
- 3
  Apply the known information to the steam flow formula: flow rate = 3600 * load / enthalpy of evaporation. This equation is based on measurements using the international system of units (SI). SI units are accepted internationally and are the units used in the fields of international science, trade and commerce.The SI is based on the metric system. The units of steam flow given by this calculation are kilograms per hour.
