A solution of a strong alkaline, such as sodium hydroxide, at concentration 1 mol dm â3, has a pH of 14. Thus, measured pH values will lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.
The Saffir-Simpson scale measures the intensity of a hurricane. Wind speed is measured on a scale of 1-5 to give an estimate of potential property damage and flooding along the coast. The Categories are as follows:Category One Hurricane: Winds 74-95 mph.Category Two Hurricane: Winds 96-110 mph.ind speed is measured on a scale of 1-5 to give an estimate of potential property damage and flooding along the coast. The Categories are as follows: Category One Hurricane: Winds 74-95 mph.
There's a thing called the Beaufort scale that doesn't really have units, and is based on water wave action at a given wind velocity. Beaufort 0 is dead calm and Beaufort 12 i â¦ s a hurricane. Knots (nautical miles per hour) is how wind is usually measured.here's a thing called the Beaufort scale that doesn't really have units, and is based on water wave action at a given wind velocity.
