1. What is Angular Momentum?

Angular Momentum is the degree to which a body rotates, gives its angular momentum. It is a vector quantity that represents the rotational equivalent of linear momentum.

2. How Does the Calculator Work?

The calculator uses the Angular Momentum formula:

Where:

• \( L \) — Angular Momentum (kg·m²/s)
• \( wf \) — Weight of Fluid (N)
• \( v \) — Velocity of Jet (m/s)
• \( G \) — Specific Gravity of Fluid
• \( r \) — Radius of wheel (m)

Explanation: The formula calculates the angular momentum at the outlet by considering the weight of fluid, its velocity, specific gravity, and the radius of the wheel.

3. Importance of Angular Momentum Calculation

Details: Accurate angular momentum calculation is crucial for analyzing rotational systems, designing turbines and pumps, and understanding fluid dynamics in mechanical systems.

4. Using the Calculator

Tips: Enter weight of fluid in Newtons, velocity of jet in m/s, specific gravity of fluid, and radius of wheel in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of angular momentum?
A: Angular momentum is measured in kilogram square meter per second (kg·m²/s).

Q2: How does specific gravity affect angular momentum?
A: Specific gravity represents the density ratio of the fluid to water. Higher specific gravity fluids will generally produce lower angular momentum for the same weight and velocity.

Q3: Can this formula be used for any fluid?
A: Yes, the formula is applicable to any fluid as long as the specific gravity is known and the units are consistent.

Q4: What is the significance of the radius in this calculation?
A: The radius determines the moment arm for the angular momentum calculation. Larger radius results in greater angular momentum for the same linear momentum.

Q5: Is angular momentum conserved in these systems?
A: In ideal systems with no external torques, angular momentum is conserved. However, real-world applications may involve energy losses.
