Formula Used in “Bernoulli Equation Calculator”
The Bernoulli Equation is a fundamental principle in fluid dynamics that relates the pressure, velocity, and elevation in a moving fluid. The standard formula is represented as follows:
Bernoulli’s Equation:
[
P + frac{1}{2} rho v^2 + rho gh = text{constant}
]
Step-by-Step Breakdown of the Formula
In the above equation, each variable represents a specific aspect of the fluid’s behavior:
- P: This is the pressure exerted by the fluid (in Pascals, Pa).
- (rho): The density of the fluid (in kilograms per cubic meter, kg/m³).
- v: The flow velocity of the fluid (in meters per second, m/s).
- g: The acceleration due to gravity (approximately 9.81 m/s²).
- h: The height of the fluid above a reference point (in meters, m).
Example Calculation
To understand how to utilize the Bernoulli Equation, let’s look at a real-world example. We will calculate the pressure at a specific point in a water flow scenario.
Input Values
Consider the following parameters for our example:
| Parameter | Value | Unit |
|---|---|---|
| Densitry (ρ) | 1000 | kg/m³ |
| Velocity (v) | 5 | m/s |
| Height (h) | 10 | m |
| Pressure (P) | Unknown | Pa |
Calculation Steps
1. Begin with the Bernoulli Equation:
[
P + frac{1}{2} rho v^2 + rho gh = text{constant}
]
2. Substitute the known values:
[
P + frac{1}{2} (1000 , text{kg/m}^3)(5 , text{m/s})^2 + (1000 , text{kg/m}^3)(9.81 , text{m/s}^2)(10 , text{m}) = text{constant}
]
3. Calculate the kinetic energy term:
[
frac{1}{2} (1000)(25) = 12500 , text{Pa}
]
4. Calculate the potential energy term:
[
(1000)(9.81)(10) = 98100 , text{Pa}
]
5. Combine these terms:
[
P + 12500 + 98100 = text{constant}
]
6. If we assume the constant is the sum of known energies, say 110000 Pa, we solve for P:
[
P + 110600 = 110000 Rightarrow P = 110000 – 110600 = -600 , text{Pa}
]
