A typical graph produced when testing the breathing performance of a diving regulator. The breathing performance of regulators is a measure of the ability of a breathing gas regulator to meet the demands placed on it at varying ambient pressures and temperatures, and under varying breathing loads, for the range of breathing gases it may be expected to deliver.
A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
A recreational diver with 50 bar of air or nitrox carried in a 12 litre cyliner will have about 0.780 kg of gas, and therefore about 0.78 litres of gas in the BC. A depth change of 1 m upwards will change ambient absolute pressure from 1.3 bar to 1.2 bar so the gas in the BC will expand to 1.3/1.2 × 0.78 = 0.845 litres, a difference of 0.065 ...
Underwater breathing apparatus can be classified as open circuit, semi-closed circuit, (including gas extenders) or closed circuit (including reclaim systems), based on whether any of the exhaled gas is recycled, and as self-contained or remotely supplied (usually surface-supplied, but also possibly from a lock-out submersible or an underwater habitat), depending on where the source of the ...
A 1964 scuba cylinder valve with reserve, commonly known as a "type J" valve. The inlet is threaded 3/4"-14 NPSM and the outlet is a standard CGA 850 yoke type. The first-stage of the scuba regulator may be connected to the cylinder valve by one of two standard types of fittings.
Is 'Tulsa King' renewed for season 3? Not yet. Deadline reports that there are talks of a two-season renewal, putting the show at 4 total seasons. However, there have been no official statements.
