1. What is Normal Thrust Parallel to Direction of Jet?

The Normal Thrust Parallel to Direction of Jet refers to the force acting perpendicular to a surface when a jet of fluid impinges on it. This calculation is essential in fluid mechanics and engineering applications involving jet propulsion and fluid impact forces.

2. How Does the Calculator Work?

The calculator uses the thrust force formula:

\[ Ft = \frac{\gamma_f \cdot A_{Jet} \cdot (V_{absolute} - v)^2}{G} \cdot \left(\angle D \cdot \frac{180}{\pi}\right) \]

Where:

\( \gamma_f \) — 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
\( \angle D \) — Angle between Jet and Plate (rad)
\( \pi \) — Mathematical constant (3.14159)

Explanation: The formula calculates the thrust force generated by a fluid jet impinging on a surface, accounting for fluid properties, velocity differences, and impact angle.

3. Importance of Thrust Force Calculation

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

4. Using the Calculator

Tips: Enter all values in appropriate units. Ensure velocity values are positive, specific gravity is greater than zero, and angle is in radians. All values must be valid for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is specific weight of liquid?
A: Specific weight refers to the weight per unit volume of a substance, typically measured in N/m³.

Q2: How is cross sectional area of jet measured?
A: Cross sectional area is the area of the jet's cross-section perpendicular to the flow direction, measured in square meters.

Q3: What's the difference between absolute velocity and jet velocity?
A: Absolute velocity is the actual velocity of the issuing jet, while jet velocity refers to the velocity of the jet relative to the surface it's impinging on.

Q4: Why is angle measured in radians?
A: Radians are the standard unit for angular measurements in mathematical calculations, providing more precise results in trigonometric functions.

Q5: What are typical applications of this calculation?
