펌프 유량 계산기

부피/시간 또는 배관 지름과 유속으로 유량을 계산합니다.

소개

Pump Flow Calculator — Flow rate from volume/time or pipe diameter & velocity. Enter Volume (L), Time (min), Pipe diameter (m, optional), Flow velocity (m/s, optional) to get an instant, accurate result.

공식

From volume and time: flow (L/min) = volume (L) / time (min). From pipe continuity: flow = pipe cross-sectional area × velocity, where area = π × (diameter/2)². Both are exact standard equations; enter either pair of inputs.

단계별 안내

  1. Enter the Volume (L).
  2. Enter the Time (min).
  3. Enter the Pipe diameter (m, optional).
  4. Enter the Flow velocity (m/s, optional).
  5. Click Calculate to see your result instantly.

실제 예시

Example: With Volume (L) = 300, Time (min) = 5, Pipe diameter (m, optional) = 0, Flow velocity (m/s, optional) = 0, the Pump Flow Calculator gives Flow Lpm: 60, Pipe Area M2: 0, Flow From Pipe Lpm: 0.

자주 묻는 질문

Which set of inputs should I use?
Use volume and time if you can measure how much water fills a container over a known time; use pipe diameter and flow velocity if you know the pipe size and water speed instead — you can fill in either pair.
Why does pipe diameter matter so much to flow rate?
Cross-sectional area scales with the square of the radius, so a modest increase in pipe diameter produces a much larger increase in flow rate at the same velocity.
What inputs does the Pump Flow Calculator need?
You'll need to provide: Volume (L), Time (min), Pipe diameter (m, optional), Flow velocity (m/s, optional). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Pump Flow Calculator?
The Pump Flow Calculator applies the formula exactly as calculated — From volume and time: flow (L/min) = volume (L) / time (min). From pipe continuity: flow = pipe cross-sectional area × velocity, where area = π × (diameter/2)². Both are exact standard equations; enter either pair of inputs. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Pump Flow Calculator free to use?
Yes, the Pump Flow Calculator is completely free, requires no signup, and runs instantly in your browser.

The Pump Flow Calculator uses a real, verifiable formula — From volume and time: flow (L/min) = volume (L) / time (min). From pipe continuity: flow = pipe cross-sectional area × velocity, where area = π × (diameter/2)². Both are exact standard equations; enter either pair of inputs. — so results are accurate every time, not an approximation.
