Kv

Coefficient calculating Kv.

Qn = Nm3/h if p2 ≥ p1/2 kv = m3/h
pn = kg/Nm3
Δp = bar if p2 < p1/2 kv = m3/h
p2 = bar
T = °C
kv=Qn/514*V((pn*T)/(deltap*p2)) for p2 ≥ p1/2
kv=Qn/(257*p1)*V(pn*T) for p2 < p1/2

Flow

Calculation of the volumetric flow rate Qn.

kv = m3/h if p2 ≥ p1/2 Qn = Nm3/h
pn = kg/Nm3
Δp = bar if p2 < p1/2 Qn = Nm3/h
p2 = bar
T = °C
Qn=514*kv*V((deltap*p2)/(pn*T)) for p2 ≥ p1/2
Qn=257*kv*p1*1/V(pn*T) for p2 < p1/2

Pressure drop

Calculating the pressure drop Delta p

kv = m3/h if p2 ≥ p1/2 Δp = bar
Qn = Nm3/h
pn = kg/Nm3 if p2 < p1/2 Impossible to calculate
p2 = bar
T = °C
deltap=(Qn^2*pn*T)/(kv^2*514^2*p2) for p2 ≥ p1/2
