Flow
Volumetric and mass flow, velocity and differential pressure.
Instrumentation and control
Volumetric flow from velocity
Q = vA→Instrumentation and controlFlow velocity
v = Q / A→Instrumentation and controlMass flow
ṁ = ρQ→Instrumentation and controlFlow from differential pressure
Q = K√Δp→Instrumentation and controlDifferential pressure from flow
Δp = (Q/K)²→Instrumentation and controlRestriction device flow
Q = CεA₂/√(1−β⁴) · √(2Δp/ρ)→
