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
Measure S and the quote "I Agree". The other showed a letter written by him on city letterhead, with "I agree" following many pro-Measure S talking points. It was headed "Mayor Garcetti finds a lot to like about Measure S". The mailer implied that Garcetti supported Measure S, which in fact he strongly opposed. He called it a "dirty trick".
