The difference between the reference and a sample is that the concentration of the measurable substance in the reference solution is zero. The reference tube transmits as much light as is possible with the solution you are using.
Rate this Article: The Saffir-Simpson Hurricane Scale is a 1-5 rating based on the hurricane's present intensity. This hurricane scale is used to give an estimate of the potential property damage and flooding expected along the coast from a hurricane landfall. Wind speed is the determining factor in the scale, as storm surge values are highly dependent on the slope of the continental shelf in the landfall region. Wind speeds are measured using a 1-minute average. Note:The Saffir-Simpson Hurricane Wind Scale (SSHWS) was updated in 2012 to accomodate number rounding issues.
The Beaufort scale has been and still is used to describe wind conditions. The max on this scale is 12 (starting at 64 knots or 74 mph) which is described as 'hurricane'. Howeâ¦ver some countries now use an extended scale with numbers beyond 12 to cover varying strengths of hurricane. Hurricanes themselves are rated on the Saffir-Simpson scale with a category 1 hurricane beginning at the same point as 12 on the Beaufort scale. It goes up to a category 5, with winds of at least 137 knots or 157 mph. Making the world better, one answer at a time.
