Steam Tube Diameter Selection and Pressure Drop Calculation in Steam Tube
There are several tables for the selection of steam tubes. However, no pressure drop has been shown in these tables. While the pressure drops in the steam pipes are calculated in accordance with the actual inner diameter of the steam pipes, the pressure drops are shown as well in the table given below.

This table has been calculated and prepared by Mustafa Aral
Pressure drops are calculated according to the formula given below:
dp = 6.753 q² L (1 + 91.4 / d) / ρ d5 [1]
where;
dp : pressure drop [bar]
q : steam flow rate [kg/h]
L : tube lenght [m]
d : inner diameter of tube [mm]
ρ : steam specific mass [kg/m3]
