1. What is Initial Velocity Given Power Delivered To Wheel?

This calculator determines the initial velocity of a fluid jet based on the power delivered to a wheel, specific gravity of the fluid, weight of fluid, final velocity, and velocity of the jet. It's commonly used in fluid mechanics and hydraulic engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ u = \left( \frac{P_{dc} \times G}{w_f \times v_f} \right) - v \]

Where:

\( u \) — Initial Velocity (m/s)
\( P_{dc} \) — Power Delivered (W)
\( G \) — Specific Gravity of Fluid
\( w_f \) — Weight of Fluid (N)
\( v_f \) — Final Velocity (m/s)
\( v \) — Velocity of Jet (m/s)

Explanation: This formula calculates the initial velocity by considering the energy transfer from the fluid to the wheel, accounting for fluid properties and velocity changes.

3. Importance of Initial Velocity Calculation

Details: Accurate initial velocity calculation is crucial for designing hydraulic systems, optimizing energy transfer efficiency, and understanding fluid dynamics in various engineering applications.

4. Using the Calculator

Tips: Enter all values in appropriate units (Power in watts, Weight in newtons, Velocities in m/s). Ensure all values are positive and physically meaningful for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is specific gravity of fluid?
A: Specific gravity is the ratio of the density of a substance to the density of a reference substance (typically water at 4°C).

Q2: Why is weight of fluid measured in newtons?
A: Weight is a force measured in newtons, which represents the gravitational force acting on the fluid mass.

Q3: What are typical values for velocity of jet?
A: Jet velocities vary widely depending on the application, but typically range from 5-50 m/s in hydraulic systems.

Q4: Can this formula be used for compressible fluids?
A: This formula is primarily designed for incompressible fluids. For compressible fluids, additional factors need to be considered.

Q5: What applications use this calculation?
A: This calculation is used in hydraulic turbines, water wheels, jet propulsion systems, and various fluid power applications.
