1. What Is Water Conductivity To Resistivity Conversion?

Water conductivity and resistivity are reciprocal parameters that measure water's ability to conduct or resist electrical current. Conductivity measures how well water conducts electricity, while resistivity measures how well it resists electrical flow.

2. How Does The Calculator Work?

The calculator uses the conversion formula:

\[ \rho = \frac{1}{\kappa} \times 10^6 \]

Where:

\( \rho \) — Resistivity in ohm-centimeters (Ω·cm)
\( \kappa \) — Conductivity in microsiemens per centimeter (μS/cm)
\( 10^6 \) — Conversion factor for units

Explanation: This formula converts between conductivity and resistivity, which are inversely related electrical properties of water.

3. Importance Of Water Quality Parameters

Details: Conductivity and resistivity measurements are crucial for assessing water purity, monitoring industrial processes, controlling water treatment systems, and ensuring compliance with water quality standards.

4. Using The Calculator

Tips: Enter conductivity value in μS/cm. The value must be greater than zero. The calculator will automatically compute the corresponding resistivity in Ω·cm.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between conductivity and resistivity?
A: Conductivity and resistivity are reciprocally related. Resistivity = 1/Conductivity (with appropriate unit conversions).

Q2: What are typical conductivity values for different water types?
A: Ultra-pure water: 0.055 μS/cm, Distilled water: 0.5-5 μS/cm, Drinking water: 50-500 μS/cm, Sea water: ~50,000 μS/cm.

Q3: Why is this conversion important in water treatment?
A: It helps monitor water purity, detect contamination, and control processes like reverse osmosis and deionization.

Q4: What factors affect water conductivity?
A: Dissolved ions, temperature, pH, and total dissolved solids (TDS) significantly influence water conductivity.

Q5: How does temperature affect the measurements?
A: Conductivity increases with temperature. Measurements are often corrected to a standard temperature (usually 25°C) for accurate comparisons.
