1. What is Mass Flow Rate?

Mass Flow Rate of Jet is defined as the flow rate of a mass per second. It represents the amount of mass passing through a given cross-sectional area per unit time, which is crucial in fluid dynamics and engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Specific\ Weight\ of\ Liquid \) — Weight per unit volume of the fluid (kN/m³)
• \( Cross\ Sectional\ Area\ of\ Jet \) — Area of the jet cross-section (m²)
• \( Fluid\ Jet\ Velocity \) — Velocity of the fluid jet (m/s)
• \( [g] \) — Gravitational acceleration constant (9.80665 m/s²)

Explanation: The formula calculates the mass flow rate by considering the specific weight of the fluid, the cross-sectional area through which it flows, and its velocity, normalized by gravitational acceleration.

3. Importance of Mass Flow Rate Calculation

Details: Accurate mass flow rate calculation is essential for designing fluid systems, optimizing energy transfer, and ensuring proper operation in various engineering applications including hydraulic systems, jet engines, and irrigation systems.

4. Using the Calculator

Tips: Enter specific weight in kN/m³, cross-sectional area in m², and fluid jet velocity in m/s. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between mass flow rate and volumetric flow rate?
A: Mass flow rate measures the mass of fluid passing through per unit time (kg/s), while volumetric flow rate measures the volume of fluid passing through per unit time (m³/s).

Q2: Why is gravitational acceleration included in the formula?
A: Gravitational acceleration is used to convert specific weight (weight-based) to mass-based units, ensuring consistency in the calculation.

Q3: What are typical units for specific weight?
A: Specific weight is typically measured in kN/m³ or N/m³, representing the weight per unit volume of the fluid.

Q4: Can this calculator be used for any fluid?
A: Yes, as long as you know the specific weight of the fluid. Different fluids have different specific weights which affect the mass flow rate.

Q5: How accurate is this calculation?
A: The calculation provides theoretical values based on ideal conditions. Actual results may vary due to factors like fluid viscosity, turbulence, and system losses.
