In the case of a secured promissory note, the lender accepts the promissory note based on the maker's ability to repay, but the note is secured by a thing of value; if the maker fails to pay and the bank reclaims payment, the lender has the right to execute the security.
Turbidity is the measure of relative clarity of a liquid. It is an optical characteristic of water and is an expression of the amount of light that is scattered by material in the water when a light is shined through the water sample.The higher the intensity of scattered light, the higher the turbidity.t is an optical characteristic of water and is an expression of the amount of light that is scattered by material in the water when a light is shined through the water sample. The higher the intensity of scattered light, the higher the turbidity.
Turbidity is measured in nephelometric turbidity units, or NTUs. Nephelometric simply means how cloudy the water is. The picture above shows different NTU values for samples of water. Drinking water must have less than 0.5 NTU, more clear then the beaker of water shown above with a 10 underneath.urbidity is a measure of how clear the water is. High turbidity means that there are a lot of particles suspended in the water and light cannot get through. Low turbidity means that there are fewer particles in the water and it is more clear. Turbidity in a stream may increase from: 1  soil erosion. 2  higher levels of algae.
