1. What is Dynamic Thrust Exerted on Plate by Jet?

Dynamic Thrust Exerted on Plate by Jet refers to the force generated when a jet of fluid impinges on a plate. This force is perpendicular to the surface of the plate and is calculated based on the fluid properties and velocities involved.

2. How Does the Calculator Work?

The calculator uses the Dynamic Thrust formula:

\[ Ft = \frac{\gamma_f \times A_{Jet} \times (V_{absolute} - v)^2}{G} \]

Where:

\( Ft \) — Thrust Force (N)
\( \gamma_f \) — Specific Weight of Liquid (N/m³)
\( A_{Jet} \) — Cross Sectional Area of Jet (m²)
\( V_{absolute} \) — Absolute Velocity of Issuing Jet (m/s)
\( v \) — Velocity of Jet (m/s)
\( G \) — Specific Gravity of Fluid

Explanation: The formula calculates the thrust force based on the difference between absolute velocity and jet velocity, squared, multiplied by specific weight and cross-sectional area, then divided by specific gravity.

3. Importance of Thrust Force Calculation

Details: Accurate thrust force calculation is crucial for designing hydraulic systems, jet propulsion systems, and understanding fluid-structure interactions in various engineering applications.

4. Using the Calculator

Tips: Enter specific weight in N/m³, cross-sectional area in m², velocities in m/s, and specific gravity as a dimensionless value. All values must be positive and valid.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between absolute velocity and jet velocity?
A: Absolute velocity refers to the actual velocity of the jet issuing from the nozzle, while jet velocity typically refers to the velocity of the plate or the relative velocity between the jet and the plate.

Q2: Why is specific gravity included in the formula?
A: Specific gravity is used to normalize the thrust force calculation relative to a standard fluid, typically water, allowing for comparisons across different fluid types.

Q3: What are typical units for specific weight?
A: Specific weight is typically measured in N/m³ (Newton per cubic meter) in the SI system.

Q4: Can this formula be used for compressible fluids?
A: This formula is primarily designed for incompressible fluids. For compressible fluids, additional factors such as density changes and compressibility effects need to be considered.

Q5: What are some practical applications of this calculation?
A: This calculation is used in hydraulic machinery, jet propulsion systems, water turbines, and various fluid power applications where jet forces on surfaces need to be determined.
