1. What is Velocity at Inlet for Mass of Fluid Striking Vane per Second?

Velocity at Inlet for Mass of Fluid Striking Vane per Second refers to the initial speed of a fluid jet as it impacts a vane or surface. This calculation is essential in fluid mechanics for determining the force and energy transfer in various engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ v = \frac{m_f \times G}{\gamma_f \times A_{Jet}} \]

Where:

\( v \) — Velocity of Jet (m/s)
\( m_f \) — Fluid Mass (kg)
\( G \) — Specific Gravity of Fluid
\( \gamma_f \) — Specific Weight of Liquid (kN/m³)
\( A_{Jet} \) — Cross Sectional Area of Jet (m²)

Explanation: This formula calculates the velocity of a fluid jet based on the mass flow rate, fluid properties, and the cross-sectional area through which the fluid flows.

3. Importance of Velocity Calculation

Details: Accurate velocity calculation is crucial for designing hydraulic systems, turbines, pumps, and other fluid machinery. It helps engineers determine the kinetic energy and impact force of fluid jets.

4. Using the Calculator

Tips: Enter fluid mass in kg, specific gravity (dimensionless), specific weight in kN/m³, and cross-sectional area in m². All values must be positive numbers.

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: How is specific weight different from density?
A: Specific weight is weight per unit volume (N/m³ or kN/m³), while density is mass per unit volume (kg/m³). They are related by gravity.

Q3: What applications use this velocity calculation?
A: This calculation is used in hydraulic turbines, water jets, spray systems, and any application where fluid impacts a surface.

Q4: What are typical velocity ranges for fluid jets?
A: Velocity ranges vary widely depending on the application, from a few m/s in irrigation systems to hundreds of m/s in high-pressure water jet cutting.

Q5: How does cross-sectional area affect velocity?
A: For a constant mass flow rate, velocity increases as cross-sectional area decreases, following the continuity equation.
