1. What is a Mass Flow Rate Calculator?

Definition: This calculator determines the mass flow rate of a fluid based on its density and volumetric flow rate.

Purpose: It's essential for engineers, physicists, and technicians working with fluid dynamics in pipes, HVAC systems, and industrial processes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( ṁ \) — Mass flow rate (kg/s)
• \( \rho \) — Fluid density (kg/m³)
• \( Q \) — Volumetric flow rate (m³/s)

Explanation: The mass flow rate is calculated by multiplying the fluid's density by its volumetric flow rate.

3. Importance of Mass Flow Rate Calculation

Details: Accurate mass flow rate calculations are crucial for system design, process control, energy calculations, and ensuring proper operation of fluid systems.

4. Using the Calculator

Tips: Enter the fluid density in kg/m³ and volumetric flow rate in m³/s. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical density for water?
A: Water at 4°C has a density of 1000 kg/m³. This decreases slightly with increasing temperature.

Q2: How do I convert from liters/second to m³/s?
A: Divide by 1000 (1 liter = 0.001 m³).

Q3: What if my flow rate is in gallons per minute?
A: First convert to m³/s (1 gpm ≈ 6.309 × 10⁻⁵ m³/s).

Q4: Does this work for gases?
A: Yes, but gas density varies with pressure and temperature, so use appropriate density values.

Q5: Why is mass flow rate important?
A: Mass flow rate is conserved (unlike volumetric flow rate) and is needed for energy and momentum calculations.
