Add the friction loss caused by each bend and enter the total on Page 1, in the appropriate space. 4. On Page 3 carefully determine the total volumetric flow rate of the exhaust gases (CFM) passing through any length of straight run duct and its equivalent diameter in order to determine the friction loss per 100 feet.

### Boiler – Fundamentals and Best Practices

Mar 17, 2015 · Step 1: Determine Properties of Steam Produced. Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow
