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.
An anemometer is a device that tells you how fast the wind is blowing. The device you can build is a model of a wind speed indicator. A real one will be able to accurately measure how fast the wind is blowing.Yours will give you only approximation of how fast it's blowing.It can't give you an exact wind speed.n anemometer is a device that tells you how fast the wind is blowing.
