Gravity Fed Water Pressure Formula:
From: | To: |
Gravity fed water pressure refers to the pressure exerted by a column of fluid due to the force of gravity. It's calculated using the formula P_g = ρgh, where ρ is fluid density, g is gravitational acceleration, and h is the height of the fluid column.
The calculator uses the hydrostatic pressure formula:
Where:
Explanation: The pressure at any point in a fluid at rest is proportional to the density of the fluid, the acceleration due to gravity, and the height of the fluid column above that point.
Details: Calculating gravity fed water pressure is essential for designing water supply systems, irrigation systems, and understanding fluid behavior in various engineering applications.
Tips: Enter fluid density in kg/m³ (1000 for water), gravitational acceleration in m/s² (9.81 on Earth), and height in meters. All values must be positive.
Q1: What is the standard value for water density?
A: The density of pure water at 4°C is approximately 1000 kg/m³.
Q2: How does temperature affect the calculation?
A: Fluid density changes with temperature. For precise calculations, use the density value at the specific temperature of interest.
Q3: What is Earth's gravitational acceleration?
A: Standard gravity on Earth is approximately 9.80665 m/s², often rounded to 9.81 m/s² for calculations.
Q4: Can this formula be used for any fluid?
A: Yes, the formula works for any fluid, but you must use the correct density value for that specific fluid.
Q5: How is this different from atmospheric pressure?
A: This calculates only the pressure due to the fluid column. Total pressure at a point would include atmospheric pressure plus the fluid pressure.
