1. What is Mass Flow Rate?

Mass flow rate is the mass of a substance that passes per unit of time, typically measured in kilograms per second (kg/s). For water, it can be calculated directly from volume flow rate since water's density is 1000 kg/m³ at standard conditions.

2. How Does the Calculator Work?

The calculator uses the simple equation:

Where:

• \( Mass\_flow \) — Mass flow rate (kg/s)
• \( Q \) — Volume flow rate (m³/s)
• 1000 — Density of water (kg/m³)

Explanation: Since water has a density of 1000 kg/m³, each cubic meter per second of flow equals 1000 kg/s of mass flow.

3. Importance of Mass Flow Calculation

Details: Mass flow rate is essential in fluid dynamics, process engineering, and system design where precise measurements of substance movement are required.

4. Using the Calculator

Tips: Enter volume flow rate in cubic meters per second (m³/s). The value must be positive.

5. Frequently Asked Questions (FAQ)

Q1: Why is the density of water 1000 kg/m³?
A: This is the standard density of water at 4°C and 1 atmosphere pressure, which is commonly used as a reference value.

Q2: Does this work for other liquids?
A: No, this calculator is specifically for water. Other liquids would require their specific density values.

Q3: What if my water is at a different temperature?
A: For precise calculations with temperature variations, you would need to account for the exact density at that temperature.

Q4: What are common applications of this calculation?
A: Used in hydraulic systems, water treatment plants, irrigation systems, and any application where water flow needs to be measured in mass terms.

Q5: How do I convert from other volume units?
A: First convert your volume flow to m³/s, then use this calculator. For example, 1 L/s = 0.001 m³/s.
