Control Valve Kv Calculator
Calculation formula: Kv = Q / √(ΔP / (ρ/1000))
Where:
Kv - throughput coefficient [m³/h]
Q - liquid flow [m³/h]
ρ - liquid density [kg/m³]
ΔP - pressure drop [bar]
Important: Density should be in kg/m³ (for water ≈1000 kg/m³)

Detailed calculation:
Note: The formula is applied to turbulent flow of incompressible fluids.For water at 20°C the density is 998 kg/m³.
