Pure oxygen is actually poisonous to humans but I don't think you're gonna get too much in an oxygen bar! I personally think that it's a complete waste of money, it can be up to a dollar a minute. I am a bio student it and it is proven that high levels of oxygen are damaging to your health and actually kills brain cells and makes you age faster... So not worth it at all!
£6.00 a hour
$10 per hour at most
Believe it or not, we can die from too little oxygen AND too much oxygen. This concept involves partial pressures. If we first consider using standard air (i.e. 20% Oxygen and 80% Nitrogen): (1 bar = 1 kilogram of pressure per square centimetre) At the surface - Total Pressure of air = 1 bar - Pressure of Oxygen = 0.2 bar - Pressure of Nitrogen = 0.8 bar At 10m - Total Pressure of air = 2 bar - Pressure of Oxygen = 0.4 bar - Pressure of Nitrogen = 1.6 bar At 20m - Total Pressure of air = 3 bar - Pressure of Oxygen = 0.6 bar - Pressure of Nitrogen = 2.4 bar At 30m - Total Pressure of air = 4 bar - Pressure of Oxygen = 0.8 bar - Pressure of Nitrogen = 3.2 bar At 40m - Total Pressure of air = 5 bar - Pressure of Oxygen = 1.0 bar - Pressure of Nitrogen = 4.0 bar At 50m - Total Pressure of air = 6 bar - Pressure of Oxygen = 1.2 bar - Pressure of Nitrogen = 4.8 bar At 60m - Total Pressure of air = 7 bar - Pressure of Oxygen = 1.4 bar - Pressure of Nitrogen = 5.6 bar At 70m - Total Pressure of air = 8 bar - Pressure of Oxygen = 1.6 bar - Pressure of Nitrogen = 6.4 bar It is at the partial pressure of 1.6 bar (which occurs at 70m where oxygen becomes toxic. That is why most dive organisations recommend 50m as a maximum for recreational diving. However, if pure oxygen is used: At surface - Pressure of Oxygen = 1 bar At 10m - Pressure of oxygen = 2 bar The oxygen has already become toxic! Hope that answers your question. The concept is called "partial pressures" and "oxygen toxicity" if you want to research more on a search engine.
ABOUT a half hour if you have done it before.
it pays by hour and the location
depends on the plant - <======3
It depends on your location.
Liters of oxygen gas per hour x 0.0353 = cubic feet per hour
Wonder Bar in Asbury Park NJ. Doggy Yappy hour is awesome :)
A single bar of an electric fire usually consumes 1000 Watts or 1 Kilo Watt (kW) Run the bar for 1 hour and you use 1 KW/Hour (1000 Watts for 1 hour) Refer to your last electricity bill where your supplier will list their charges in KW Hrs. I would imagine around 25 cents? per Kwh
Bill Miller's pays around 9 dollars per hour.
The thermal conductivity of oxygen is 24,24 mW/mK at 1,013 bar and 0 0C.
