Head Formula:
| From: | To: |
Pressure to head conversion is a fundamental concept in fluid mechanics that converts pressure measurements to equivalent height of a fluid column. This conversion is essential in various engineering applications, particularly in hydraulics and pump systems.
The calculator uses the head formula:
Where:
Explanation: The formula converts pressure to the equivalent height of a fluid column based on the fluid's density and gravitational force.
Details: Head calculation is crucial for designing pumping systems, analyzing pipe networks, and understanding fluid behavior in various engineering applications. It helps engineers determine the energy required to move fluids through systems.
Tips: Enter pressure in Pascals, fluid density in kg/m³. All values must be positive numbers. The gravitational constant is fixed at 9.8 m/s².
Q1: What is the physical meaning of head?
A: Head represents the height of a fluid column that would produce the given pressure at its base. It's a measure of fluid energy per unit weight.
Q2: Why use head instead of pressure?
A: Head is independent of fluid density, making it useful for comparing systems with different fluids or for pump performance curves.
Q3: What are typical head values in engineering?
A: Head values vary widely depending on application. Residential water systems might have heads of 20-50 meters, while industrial pumps can handle heads of hundreds of meters.
Q4: Can this calculator be used for any fluid?
A: Yes, as long as you know the fluid's density. The formula works for water, oil, chemicals, and other liquids.
Q5: How does temperature affect head calculation?
A: Temperature affects fluid density. For accurate results, use the density value at the operating temperature of your system.
