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.
wind speed is the rate at which air flows past a point above the earth s surface wind speed can be quite variable and is determined by a number of factors which will be discussed in this sectionwind power wind power is a measure of the energy available in the windit is a function of the cube third power of the wind speed if the wind speed is doubled power in the wind increases by a factor of eight 23he amount of power available in the wind is determined by the equation w 1 2 r a v3 where w is power r is air density a is the rotor area and v is the wind speed
