Final answer:
An Olympic standard swimming pool has 10 lanes with 8 used for competition, conforming to FINA's long course pool standards.
Step-by-step explanation:
An Olympic standard swimming pool typically has 10 lanes, although only 8 are used for competition. This ensures fair conditions for all swimmers by reducing the effects of waves. Olympic swimming events take place in a pool that measures 50 meters in length, which is considered a "long course" pool.
The International Swimming Federation (FINA) sets the standards for Olympic swimming competitions, including pool dimensions and the number of lanes. Regarding the volume of an Olympic-sized swimming pool, 2,500,000 liters of water could be more conveniently expressed as 2.5 megaliters (ML).
For the calculations involving swimming pool capacities and filling times, understanding conversion between units and rates is crucial. In contrast, a moderate size river flowing at 5000 cubic meters per second could theoretically fill the same pool almost instantaneously due to the vastly greater flow rate.
