Pressure Drop/ Flowrate Calculator
Input the data for the following (input only numbers):
(If the Darcy Friction factor is known, replace the value of 'e' with 'f num'
where 'num' is the friction factor.)
Diameter (meters):
Pipe Roughness (e) (meters):
Elevation Change (meters):
Pipe Length (meters):
Fluid Viscosity (kg/(m*s)):
Fluid Density (kg/m^3):
Tolerance (no units):
Volumetric Flow Rate (Q) (m^3/s):
This field is for
K Losses
(minor losses) due to geometry.
You can enter the value directly in the K value window or use the calculator
to add up K values if there is more than one.
Add up K values
K Value:
If the Flow Rate (Q) is unknown but the pressure drop is,
fill in this information:
Total Pressure Drop (kPa)
Qstep
Qtol
kPa/m
(Be careful with these values, or the system may not converge.)
Enter any work done
BY
the system (kW):
(Work done
ON
the system is negative) (This may make it more difficult to converge on Q)
