Pressure Formula:
From: | To: |
Definition: This calculator determines the hydrostatic pressure at a certain depth in a fluid column based on fluid density, height, and gravitational acceleration.
Purpose: It helps engineers and technicians calculate pressure in pipelines, tanks, and other fluid systems.
The calculator uses the formula:
Where:
Explanation: The pressure increases linearly with depth and depends on the fluid's density and local gravity.
Details: Accurate pressure calculations ensure pipeline integrity, proper pump selection, and safety in fluid systems.
Tips: Enter the fluid density in kg/m³, height/depth in meters, and gravitational acceleration (default 9.81 m/s²). All values must be > 0.
Q1: What units does this calculator use?
A: The calculator uses SI units - Pascals for pressure, kg/m³ for density, and meters for height.
Q2: Does this account for atmospheric pressure?
A: No, this calculates only hydrostatic pressure. For absolute pressure, add atmospheric pressure (101325 Pa at sea level).
Q3: What's a typical fluid density for water?
A: Pure water at 4°C has a density of 1000 kg/m³. This decreases slightly with temperature increase.
Q4: When would I change the gravity value?
A: For extreme precision or for locations with significantly different gravity (e.g., high altitude or planetary calculations).
Q5: How does pipe diameter affect the pressure?
A: Pipe diameter doesn't affect hydrostatic pressure, but it affects flow rate and dynamic pressure in moving fluids.
