Water Pressure Formula:
From: | To: |
Definition: This calculator determines the hydrostatic pressure at a certain depth in a water column or pipe using fundamental physics principles.
Purpose: It helps engineers, plumbers, and technicians calculate water pressure for system design, troubleshooting, and safety assessments.
The calculator uses the hydrostatic pressure formula:
Where:
Explanation: Pressure increases linearly with depth due to the weight of the water above.
Details: Accurate pressure calculations ensure proper pipe sizing, pump selection, and system safety to prevent leaks or bursts.
Tips: Enter water density (default 1000 kg/m³), gravity (default 9.81 m/s²), and height/depth in meters. All values must be > 0.
Q1: Why is water density typically 1000 kg/m³?
A: This is the density of pure water at 4°C. It can vary slightly with temperature and impurities.
Q2: When would I change the gravity value?
A: Only for extreme precision or calculations in different gravitational environments (e.g., space applications).
Q3: Does this account for atmospheric pressure?
A: No, this calculates only hydrostatic pressure. Total pressure would add atmospheric pressure (101325 Pa at sea level).
Q4: How does pipe diameter affect the pressure?
A: Pipe diameter doesn't affect static pressure at a given depth, but affects flow rate and dynamic pressure.
Q5: What's the practical application of this calculation?
A: Used for designing water supply systems, dams, swimming pools, and determining pump requirements.
