Head Drop (Δh) Calculation

A: Area
C: Discharge coefficient
d: density ( water density = 1000kg/m³ )
D: Diameter
g: Gravity 9.8 m/s²
K: Flow coefficient (Kv)(Cv)
Q: Flow rate
SG: Specific gravity (1 for water)
v: Flow velocity
Δh: Head Drop (high of fluid)
ΔP: Pressure Drop

Ecuaciones Diferencia de Altura Manométrica
Δh = / (K·d· g )
K = Cv, when K is referenced in [gpm] [psi] units.
K = Kv, when K is referenced in [m³/h] [bar] units.

Ecuaciones Diferencia de Altura Manometrica
Δh= [Q/ (C·A)]² · ( 1 / ( 2 ·g))

Ecuaciones Diferencia de Altura Manometrica
Δh= [Q/ (C· (D)²·π/4)]^2 · ( 1 / (2·g))
