Calculation Results

The calculated Flow Coefficient (Cv) is:

Precisely determine the Flow Coefficient (Cv) for valves and pipelines using our online calculator. Input flow rate, pressure drop, and specific gravity to understand fluid dynamics and optimize system performance efficiently. Ideal for engineers, fluid system designers, and anyone working with liquid flow systems. Get instant, accurate Cv values for water and other liquids.

Formula:

Cv = Q × √(SG / ΔP)
Where:
Q = Flow Rate (US Gallons Per Minute - GPM)
SG = Specific Gravity (dimensionless, approximately 1 for water)
ΔP = Pressure Drop (Pounds Per Square Inch - PSI)
