1. What is Pressure Using Pressure Head?

Pressure Using Pressure Head refers to the calculation of fluid pressure based on the specific weight of the liquid and the height of the liquid column (pressure head). This is fundamental in fluid mechanics for steady non-viscous flow conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_h \) — Pressure of Fluid (Pa)
• \( \gamma_f \) — Specific Weight of Liquid (N/m³)
• \( h_p \) — Pressure Head (m)

Explanation: The pressure exerted by a fluid column is directly proportional to both the specific weight of the fluid and the height of the fluid column.

3. Importance of Pressure Calculation

Details: Accurate pressure calculation is crucial for designing hydraulic systems, understanding fluid behavior in pipes and containers, and ensuring proper functioning of fluid-based machinery.

4. Using the Calculator

Tips: Enter specific weight in N/m³ and pressure head in meters. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is specific weight of a liquid?
A: Specific weight is the weight per unit volume of a substance, typically measured in N/m³.

Q2: How is pressure head different from static head?
A: Pressure head specifically refers to the height of liquid column that would produce the given pressure, while static head may include other factors.

Q3: Does this formula work for all fluids?
A: This formula works for incompressible fluids under steady non-viscous flow conditions.

Q4: What are typical units for pressure calculation?
A: Pressure is typically measured in Pascals (Pa), but can also be expressed in bars, psi, or other pressure units with appropriate conversions.

Q5: When is this calculation most applicable?
A: This calculation is most applicable for ideal fluid conditions where viscosity effects are negligible and flow is steady.
