Pressure Formula:
From: | To: |
Head to pressure conversion calculates the pressure generated by a fluid column based on its height (head), density, and gravitational acceleration. This fundamental principle is essential in fluid mechanics and pump system design.
The calculator uses the pressure formula:
Where:
Explanation: The formula calculates the hydrostatic pressure at the bottom of a fluid column, representing the pressure a pump must overcome to achieve a specific head.
Details: Accurate pressure calculation is crucial for pump selection, pipeline design, and ensuring proper system operation in various engineering applications including water supply, HVAC, and industrial processes.
Tips: Enter fluid density in kg/m³ (water ≈ 1000 kg/m³), gravitational acceleration (standard is 9.81 m/s²), and head height in meters. All values must be positive numbers.
Q1: What is the relationship between head and pressure?
A: Head and pressure are directly proportional through the fluid density and gravity. Higher head or denser fluid results in higher pressure.
Q2: Why use Pascals as the pressure unit?
A: Pascals are the SI unit for pressure, providing consistency in engineering calculations. 1 Pa = 1 N/m².
Q3: What is typical water density?
A: Pure water at 4°C has density of 1000 kg/m³. Density varies with temperature and impurities.
Q4: Can I use different gravity values?
A: Yes, for locations with different gravitational acceleration or for calculations involving centrifugal forces.
Q5: How accurate is this calculation?
A: This provides theoretical hydrostatic pressure. Actual system pressure may vary due to friction losses, pump efficiency, and other factors.
