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)

Reynolds Number	Darcy Friction Factor
Iterations used to find f	Pressure Drop Per Length kPa/m
