Please give me the formula for measuring turbidity. I already know about the wikipedia defintion and explanation.
Thanks
You need to be more specific. Turbidity of what and how are you measuring it?
Here's is what I did:
Collect water samples from Farm Lane bridge (500 mL minimum)þ
Filter water samples using small mesh filter
Note: Weigh the dried filter before filtration!
Dry the filter in drying oven (~24 hours)þ
Weigh the filter after drying.
Do I measure turbidity using a before and after measurment of my water samples?
To measure turbidity, you can use a turbidimeter, which is a device specifically designed for this purpose. The most common method of measuring turbidity is by using a nephelometer or a turbidity meter. These devices work by shining a light through a sample and measuring the amount of light scattered by suspended particles in the liquid.
The formula for measuring turbidity is based on the principles of light scattering. Here is the simplified formula:
Turbidity = K * I
Where:
- Turbidity is the measure of the clarity or haziness of a liquid (expressed in NTU, Nephelometric Turbidity Units).
- K is the calibration factor of the specific turbidity meter used.
- I is the intensity of the light scattered by the suspended particles in the liquid.
Keep in mind that different devices may have slightly different calculation methods and calibration factors, so it is important to refer to the specific instructions and calibration standards provided by the manufacturer of the turbidity meter you are using. By following those instructions, you can ensure accurate and standardized turbidity measurements.
