Flow Rate Nasıl Hesaplanır?

learn.whatIsHeading

Flow rate (Q) is the volume of fluid passing a cross-section per unit time. The continuity equation Q = A × v is fundamental to plumbing, HVAC, hydraulics, and engineering.

Formül

Q = A × v | Q = V/t | where Q = volumetric flow rate, A = cross-section area, v = velocity, V = volume, t = time

Q: Volumetric flow rate (m³/s or L/min)
A: Cross-sectional area (m²)
v: Fluid velocity (m/s)
V: Total volume (m³)
t: Time elapsed (s)

Adım Adım Kılavuz

1Q = A × v (m³/s; A in m², v in m/s)
2Continuity: A₁v₁ = A₂v₂ (fluid speeds up in narrower sections)
31 m³/s = 1,000 L/s = 60,000 L/min

Giriş

Pipe area 0.03m², velocity 2m/s

Sonuç

Q = 0.03 × 2 = 0.06 m³/s = 60 L/s = 3,600 L/min
