Indoor Swimming Pool. Respiratory risks of indoor swimming pools can include coughing, wheezing, aggravated asthma, [1] and airway hyper-responsiveness (spasms of the bronchial tubes in the lungs causing coughing and chest tightness).
A diver switching their demand valves, or using a buddy’s air supply, or repeatedly purging a rebreather may indicate the onset of SIPE, particularly if there is an adequate supply pressure, and may signal that they are out of gas, or reject a working alternative gas supply [3] A diver may have difficulty breathing at the surface.

If an NPSH A is say 10 bar then the pump you are using will deliver exactly 10 bar more over the entire operational curve of a pump than its listed operational curve. Example: A pump with a max. pressure head of 8 bar (80 metres) will actually run at 18 bar if the NPSH A is 10 bar. i.e.: 8 bar (pump curve) plus 10 bar NPSH A = 18 bar.
The even more specific problem is that, in shallower pools, the water that swimmers displace with their strokes can essentially bounce off the bottom of the pool and make the second 50 meters of a ...
Water is forced through a filter and then returned to the pool. Using a water pump by itself is often not sufficient to completely sanitize a pool. Commercial and public pool pumps usually run 24 hours a day for the entire operating season of the pool. Residential pool pumps are typically run for 4 hours per day in winter (when the pool is not ...
Davey & Jonesie's Locker is a science fiction teen comedy television series created by Evany Rosen and co-commissioned by Amazon Prime Video and Hulu. The series stars Veronika Slowikowska and Jaelynn Thora Brooks as two high school students who discover that their locker is a portal to the multiverse .
A hydraulic ram pump, ram pump, or hydram is a cyclic water pump powered by hydropower. It takes in water at one " hydraulic head " (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate.
The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. In these rotary implements ...
