    An Olympic-size swimming pool holds over 2 acre-feet of water For larger volumes of liquid, one measure commonly used in the media in many countries is the Olympic-size swimming pool. [47] A 50 m × 25 m (164 ft × 82 ft) Olympic swimming pool, built to the FR3 minimum depth of 2 metres (6.6 ft) would hold 2,500 m 3 (660,000 US gal).

    The lakes contain about 84% of the surface freshwater of North America; [48] if the water were evenly distributed over the entire continent's land area, it would reach a depth of 5 feet (1.5 meters). [49] This is enough water to cover the 48 contiguous U.S. states to a uniform depth of 9.5 feet (2.9 m).

    So, if there is a depth of 3 feet, the flow rate is ≈ 140 ft 3 /s Approximate the discharge using the derived discharge equation shown above (Equation 5). This equation was derived using the principles of specific energy and is only to serve as an estimate for the actual discharge of the Parshall flume.

  9. Speed of sound - Wikipedia

    en.wikipedia.org/wiki/Speed_of_sound

    For example, for a typical steel alloy, K = 170 GPa, G = 80 GPa and p = 7700 kg/m 3, yielding a compressional speed c solid,p of 6,000 m/s. [11] This is in reasonable agreement with c solid,p measured experimentally at 5,930 m/s for a (possibly different) type of steel. [21] The shear speed c solid,s is estimated at 3,200 m/s using the same ...
