유체 압력 계산기

대기압을 포함한 특정 깊이에서의 절대 압력.

소개

Fluid Pressure Calculator — Absolute pressure at depth including atmosphere. Enter Fluid density (kg/m³), Depth (m), Gravity (m/s²), Atmospheric pressure (Pa) to get an instant, accurate result.

공식

Total fluid pressure at a given depth is calculated as P = ρ × g × h + P_atm, where ρ is fluid density, g is gravitational acceleration, h is depth, and P_atm is atmospheric pressure (101,325 Pa at sea level).

단계별 안내

  1. Enter the Fluid density (kg/m³).
  2. Enter the Depth (m).
  3. Enter the Gravity (m/s²).
  4. Enter the Atmospheric pressure (Pa).
  5. Click Calculate to see your result instantly.

실제 예시

Example: With Fluid density (kg/m³) = 1000, Depth (m) = 2, Gravity (m/s²) = 9.81, Atmospheric pressure (Pa) = 101325, the Fluid Pressure Calculator gives Pressure Pa: 120945.

자주 묻는 질문

Why is atmospheric pressure included in this calculation?
This calculator gives absolute pressure, which includes the weight of the atmosphere pressing down on the fluid surface in addition to the pressure from the fluid column itself.
What is the difference between this and hydrostatic pressure?
Hydrostatic pressure (ρgh) is the gauge pressure from the fluid column alone. Fluid pressure here adds atmospheric pressure to give the total absolute pressure at depth.
What standard atmospheric pressure value is used?
This calculator uses 101,325 pascals (Pa), the standard atmospheric pressure at sea level, as defined by international convention.
What inputs does the Fluid Pressure Calculator need?
You'll need to provide: Fluid density (kg/m³), Depth (m), Gravity (m/s²), Atmospheric pressure (Pa). 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 Fluid Pressure Calculator?
The Fluid Pressure Calculator applies the formula exactly as calculated — Total fluid pressure at a given depth is calculated as P = ρ × g × h + P_atm, where ρ is fluid density, g is gravitational acceleration, h is depth, and P_atm is atmospheric pressure (101,325 Pa at sea level). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Fluid Pressure Calculator free to use?
Yes, the Fluid Pressure Calculator is completely free, requires no signup, and runs instantly in your browser.

The Fluid Pressure Calculator uses a real, verifiable formula — Total fluid pressure at a given depth is calculated as P = ρ × g × h + P_atm, where ρ is fluid density, g is gravitational acceleration, h is depth, and P_atm is atmospheric pressure (101,325 Pa at sea level). — so results are accurate every time, not an approximation.
