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.
Also, the units of knots were invented over a water surface to help with navigation. Being able to convert miles per hour to knots and vice versa is important. The surface wind speed in knots is multiplied by 1.15 to get the speed in miles per hour.A 100 knot wind is equal to 115 miles per hour while a 10 knot wind is equal to 11.5 miles per hour. Therefore, the stronger the wind the greater the difference between the numerical value of miles per hour and knots.Here are some of the answers to the questions posed above.lso, the units of knots were invented over a water surface to help with navigation. Being able to convert miles per hour to knots and vice versa is important. The surface wind speed in knots is multiplied by 1.15 to get the speed in miles per hour.
