1. What is Inlet Velocity in Nozzle?

Inlet velocity in nozzle is defined as the velocity of fluid entering the vessel or nozzle. It is calculated by dividing the volumetric flow rate by the inlet cross-sectional area of the nozzle.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( U_{inlet} \) — Inlet Velocity (m/s)
• \( V_{Flow} \) — Volumetric Flow Rate (m³/s)
• \( A_{inlet} \) — Inlet Area (m²)

Explanation: This formula calculates the velocity at which fluid enters a nozzle based on the flow rate and the cross-sectional area of the inlet.

3. Importance of Inlet Velocity Calculation

Details: Calculating inlet velocity is crucial for fluid dynamics analysis, nozzle design, and ensuring proper flow characteristics in various engineering applications.

4. Using the Calculator

Tips: Enter volumetric flow rate in m³/s and inlet area in m². Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the inputs?
A: Use cubic meters per second (m³/s) for volumetric flow rate and square meters (m²) for inlet area.

Q2: Why is inlet velocity important in nozzle design?
A: Inlet velocity affects flow characteristics, pressure drop, and overall efficiency of the nozzle system.

Q3: Can this calculator be used for compressible fluids?
A: This formula is primarily for incompressible fluids. For compressible fluids, additional factors need to be considered.

Q4: What if my inlet area is not circular?
A: The formula works for any cross-sectional shape as long as you use the correct area measurement.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise based on the inputs provided, assuming ideal flow conditions.
