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)
