1. What Is Moisture Content?

Moisture Content (MC) is a measurement of the amount of water present in a material compared to its dry mass. It's expressed as a percentage and is widely used in agriculture, construction, food processing, and many other industries.

2. How Does the Calculator Work?

The calculator uses the Moisture Content formula:

Where:

• \( MC \) — Moisture Content (%)
• \( m_{wet} \) — Mass of wet sample (kg)
• \( m_{dry} \) — Mass of dry sample (kg)

Explanation: The formula calculates the percentage of water mass relative to the dry mass of the material.

3. Importance of Moisture Content Calculation

Details: Knowing moisture content is essential for quality control, shelf life determination, material processing, and ensuring product consistency in various industries.

4. Using the Calculator

Tips: Enter both wet mass and dry mass in kilograms. The wet mass must be greater than or equal to the dry mass. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between wet basis and dry basis moisture content?
A: This calculator uses dry basis (common in most industries). Wet basis expresses water as percentage of total wet mass.

Q2: How do I properly measure dry mass?
A: Dry the sample in an oven at 105°C until constant weight is achieved (typically 24 hours for most materials).

Q3: What are typical moisture content values?
A: Varies widely by material - grains (12-14%), wood (6-20%), soils (5-40%), food products often below 10%.

Q4: Can I use different units besides kilograms?
A: Yes, as long as both masses are in the same units, the calculation will be correct.

Q5: What if my wet mass is less than dry mass?
A: This shouldn't happen - check your measurements. Dry mass should never exceed wet mass.
