Pressure loss in steam pipe
- working example with ePF Loop program (Windows)
Application example: Pressure drop in steam pipe
Steam Boiler System design:
Steam pressure = 10 bar absolute
Steam saturated temperature = 179.9 oC
Steam flow rate = 8 kg/s = 93,203.88 LPM
Steam density = 5.15 kg/m3
Steam dynamic viscosity = 0.015 cP
Pipe diameter = 0.254m
Total pipe length = 500m (including valves and fittings equivalent length)
Pipe material: Steel
Applied Working:
Density and dynamic viscosity of steam at the given steam pressure is determined separately from steam application software.
Rule of thumb: Darcy-Weisbach equation is for incompressible flow for liquids. Steam is a compressible gas. Darcy-Weisbach incompressible flow equation for liquids can be used to estimate the pressure loss for gases if the calculated pressure drop is less than 10% of the upstream absolute pressure. The result is less conservative. Actual calculation using compressible flow equation for gases will yield a slightly higher pressure drop. See results calculated using Compressible, Isothermal flow equation.
