Pressure Head Formula:
| From: | To: |
Pressure Head is the vertical height of the free surface above any point in a liquid at rest. It represents the pressure energy per unit weight of the fluid at that point.
The calculator uses the Pressure Head formula:
Where:
Explanation: The formula calculates the equivalent height of a fluid column that would produce the given pressure at the point of measurement.
Details: Pressure head calculation is essential in fluid mechanics and hydraulics for determining pressure distribution, designing piping systems, and analyzing fluid behavior in various engineering applications.
Tips: Enter pressure in Pascal and specific weight in N/m³. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the physical significance of pressure head?
A: Pressure head represents the height of a fluid column that the pressure could support, converting pressure energy into equivalent potential energy.
Q2: How does pressure head relate to total head in fluid flow?
A: In Bernoulli's equation, total head consists of pressure head, velocity head, and elevation head, representing the total energy per unit weight.
Q3: What units should be used for accurate calculation?
A: Use consistent SI units - pressure in Pascal (N/m²) and specific weight in Newton per cubic meter (N/m³) for pressure head in meters.
Q4: Can this calculator be used for any fluid?
A: Yes, as long as you know the specific weight of the fluid. Different fluids have different specific weights affecting the pressure head calculation.
Q5: What is the difference between pressure head and static head?
A: Pressure head specifically refers to the pressure energy component, while static head typically refers to the elevation difference in a system.
