Conductor Calculations 

This module will calculate the Cv of a conductor and the flow through that conductor for a given upstream and downstream pressure. It will also take into consideration the number of 90 degree elbows in the conductor. 

Upstream Pressure, Suggested Delta P, Specific Gravity for Air, Air Temperature, Conductor Length, Conductor Inside Diameter, Conductor Friction Factor & KValue and Number of 90 Degree Elbows in Conductor. 

Upstream Pressure (PSIG)  The minimum pressure that is available at the inlet of the conductor. Suggested Delta P (PSI)  Pressure drop from one end of the conductor to the other. If a Delta P is above a critical flow that is entered, the calculated answer will assume critical flow. Specific Gravity for Air  The specific gravity for air is 1 at standard conditions. This can be affected somewhat by humidity and temperature. These have a minimal effect and therefore a specific gravity of 1 is normally used. Air Temperature (°F)  The air temperature is in degrees Fahrenheit. Standard conditions use 68 degrees Fahrenheit. Conductor Length (in)  The length of the entire conductor. Add sections between elbows together to arrive at total length. Conductor I.D. (in)  The inside diameter of the conductor. Friction Factor  The friction factor for the particular conductor chosen. No. of Elbows in Conductor  The number of 90 degree elbows in the conductor. Count each Tee as one elbow if airflow makes a 90 degree turn. Conductor K Value  Fitting value established for a type of conductor and fitting.
