Fluid pressure is force exerted per unit area. It increases with depth due to the weight of fluid above, creating hydrostatic pressure.
공식
The calculator applies P = P₀ + ρgh
- P
- P₀ + ρgh — P₀ + ρgh
단계별 가이드
- 1Enter fluid density, gravitational acceleration, and depth
- 2The calculator applies P = P₀ + ρgh
- 3Results show pressure at depth
풀어진 예시
입력
ρ = 1000 kg/m³ (water), g = 9.81 m/s², h = 10 m
결과
P = 98.1 kPa gauge pressure
Absolute: 199.2 kPa
피해야 할 일반적인 실수
- ✕Confusing gauge and absolute pressure
- ✕Using depth instead of vertical distance in pressure calculations
자주 묻는 질문
Why does pressure increase linearly with depth?
Each additional meter of fluid adds the same weight per unit area, creating linear pressure increase.
What's the difference between gauge and absolute pressure?
Gauge pressure measures above atmospheric pressure; absolute pressure includes atmospheric contribution.
