Anemometer in pressure of the two lines. The measurement devices can be manometers, pressure transducers, or analog chart recorders. In the tube anemometer the dynamic pressure is actually being measured, although the scale is usually graduated as a velocity scale. If the actual air density differs from the calibration value, due to differing temperature, elevation or barometric pressure, a correction is required to obtain the actual wind speed. Approximately 1.5% (1.6% above 6,000 feet) should be added to the velocity recorded by a tube anemometer for each 1000 ft (5% for each kilometer) above sea-level. At airports, it is essential to
What Difference Does It Make? of the Smiths'. The character Ray Smith in the Jack Kerouac novel "The Dharma Bums" repeatedly says "What difference does it make?" as well as "Pretty girls make graves", the title of another track featured on "The Smiths". The single cover is a photograph of Terence Stamp, taken on the set of the film "The Collector". Originally Stamp denied permission for the still to be used, and some pressings featured Morrissey in a re-enacted scene.
