1. What is Specific Gravity of Polymer?

Definition: Specific Gravity of Polymer is defined as the ratio of the density of the polymer to the density of a standard substance (usually water).

Purpose: This calculation helps in determining the concentration and quality of polymer solutions used in various industrial applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G_p \) — Specific Gravity of Polymer
• \( P \) — Polymer Feed Rate (kg/s)
• \( P_v \) — Volumetric Polymer Feed Rate (m³/s)
• \( \%P \) — Percent Polymer Concentration (as decimal)

Explanation: The formula calculates the specific gravity by dividing the polymer feed rate by the product of 8.34 (conversion factor), volumetric feed rate, and polymer concentration.

3. Importance of Specific Gravity Calculation

Details: Knowing the specific gravity helps in quality control, process optimization, and ensuring proper polymer concentration in solutions.

4. Using the Calculator

Tips: Enter the polymer feed rate in kg/s, volumetric feed rate in m³/s, and polymer concentration in percentage. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of 8.34 in the formula?
A: 8.34 is a conversion factor that accounts for the density of water (8.34 lb/gal) and unit conversions.

Q2: What's a typical polymer concentration range?
A: Polymer concentrations typically range from 0.1% to 2% depending on the application.

Q3: How accurate is this calculation?
A: The calculation is accurate when proper measurements are taken, but actual values may vary slightly due to temperature and other factors.

Q4: Can this be used for all types of polymers?
A: Yes, but the specific gravity range will vary depending on the polymer type.

Q5: What if my polymer concentration is very low?
A: For very low concentrations (<0.1%), ensure your measurements are precise as small errors can significantly affect the result.
