Pressure Head refers to the height of a liquid column that corresponds to a particular pressure exerted by the liquid column on the base of its container. It's a fundamental concept in fluid mechanics that relates pressure to equivalent height of fluid.
The calculator uses the formula:
Where:
Explanation: The formula converts fluid pressure into equivalent height of fluid column by dividing the pressure by the specific weight of the liquid.
Details: Pressure head calculation is crucial in hydraulic engineering, fluid mechanics, and various industrial applications where understanding the relationship between pressure and fluid height is essential for system design and analysis.
Tips: Enter pressure of fluid in Pascal and specific weight of liquid 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 would produce the given pressure at its base, providing an intuitive way to understand and compare pressures in fluid systems.
Q2: How does specific weight differ from density?
A: Specific weight is weight per unit volume (N/m³), while density is mass per unit volume (kg/m³). Specific weight = density × gravitational acceleration.
Q3: 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, so the pressure head will vary accordingly.
Q4: What are typical units for pressure head?
A: Pressure head is typically measured in meters (m) or feet (ft) of fluid column, representing the equivalent height of fluid.
Q5: How is pressure head used in Bernoulli's equation?
A: In Bernoulli's equation, pressure head is one of the three energy components along with elevation head and velocity head, representing the energy due to fluid pressure.
