1. What is Flow Velocity Given Power Lost?

Flow Velocity Given Power Lost calculates the velocity of fluid flow by accounting for power losses in the system. It's derived from the relationship between absolute jet velocity, power loss, fluid density, and flow rate.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Flow Velocity = Absolute Velocity of Issuing Jet - \sqrt{\frac{Power Loss}{Density of Fluid \times Rate of Flow \times 0.5}} \]

Where:

\( V \) — Absolute Velocity of Issuing Jet (m/s)
\( Ploss \) — Power Loss (W)
\( ρFluid \) — Density of Fluid (kg/m³)
\( qflow \) — Rate of Flow (m³/s)

Explanation: This formula calculates the actual flow velocity by subtracting the velocity component corresponding to power losses from the absolute jet velocity.

3. Importance of Flow Velocity Calculation

Details: Accurate flow velocity calculation is essential for designing efficient fluid systems, optimizing energy consumption, and minimizing power losses in hydraulic and pneumatic systems.

4. Using the Calculator

Tips: Enter absolute velocity in m/s, power loss in watts, fluid density in kg/m³, and flow rate in m³/s. All values must be positive numbers.
