Calculate the pressure exerted by a fluid at a given depth using its density, depth, and gravitational acceleration.
Input Parameters
How to Use Fluid Pressure Calculator?
To use the Fluid Pressure Calculator effectively, follow these steps:
- Field Explanation: Enter the **density** of the fluid in kg/m³, the **gravitational acceleration** in m/s² (usually 9.81 m/s² on Earth), and the **height** or depth of the fluid column in meters.
- Result Interpretation: The calculator will output the fluid pressure in Pascals (Pa). For example, if you input 1000 kg/m³ for density, 9.81 m/s² for gravity, and 10 m for height, the result will be 98,100 Pa.
- Tips: Ensure you input values in the correct format and units. Double-check your inputs for accuracy to prevent calculation errors.
Backend Formula for the Fluid Pressure Calculator
The formula used by our calculator is:
Pressure = Density × Gravity × Height
Step-by-Step Breakdown: The pressure exerted by a fluid is calculated by multiplying the fluid’s density (mass per unit volume) by the gravitational force acting on it, and then by the height of the fluid column.
Illustrative Example: Consider a fluid with a density of 1,000 kg/m³, under standard gravity of 9.81 m/s², and a column height of 10 m. The pressure is calculated as 1,000 × 9.81 × 10 = 98,100 Pa.
Common Variations: In some situations, variations in gravitational acceleration or fluid density may require adjustments to the formula, but our calculator assumes standard Earth gravity for simplicity.
