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 housing, that local labor be used on them, and incentivized developers for building near the city's subway lines. The city's business community, particularly developers, were as opposed to it as they were to Measure S. However, so was the CPLA. In a news release strongly opposing JJJ, it claimed that initiative had been "cooked up" by the interests opposing Measure S in an effort to split its support and keep it from the ballot. Measure S proponents said that they considered JJJ likely to fall short of its goals, pointing to what they considered broadly worded loopholes in JJJ. "Ultimately
