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.
What is the difference the way hurricanes are classified and the way tornadoes are classified? Hurricanes are classified based directly on wind speed from Category 1 to category 5 on the Saffir-Simpson scale. Tornadoes are rated based on damage-derived wind estimates, â¦ which are used to rate them on the Enhanced Fujita Scale from EF0 to EF5.
