How much is a Charles Raymond no 4379 watch worth?
How much is Charles Raymond touch screen water resistant 3atm no.8165
The pressure of x mL of a gas was increased from 2 atm to 3 atm at constant temperature what will be the new volume?
P1V1 = P2V2 P1 = 2atm V1 = xmL P2 = 3atm V2 = ? Solve for V2: P1V1/P2 = V2 (2atm)(x mL)/3atm = 2/3x mL
A 2 liters tank contains air at 1atm and 20 degrees celsius.the tank is sealed and heated until the pressure is 3 atm.what is the temperature in degrees celsius?
P=3atm=3(101325)pa V=2 liters=2000cm^3 T=20=293K (P.V)/(T)=(p.V)/t t=897K=606 degree celsius
How deep in water is 3atm of pressure?
One atmosphere is the amount of pressure that can lift water approximately 10.3 meters.Considering that a diver already experiences 1 ATM of pressure in air, the water depth in meters d, at which the diver would experience n ATM of pressure, isd = (n - 1) * 10.3Hence, to experience 3 atmospheres of pressure, you'd need to go ((3-1) * 10.3) = 20.6 meters (67.6 feet) underwater.
What is partial pressure of CO2 scuba diving?
Let's start with understanding the question. Partial pressure is defined as the fractional percentage of the gas in the overall gas mixture times the total pressure in Atmospheres. If we assume we're scuba diving using air as our breathing gas, then the fractional percentage of nitrogen is 79% (or .79). Oxygen make up the majority of the balance at 21% (.21) Air is made up primarily of these two gasses. All other gasses that comprise air are considered "trace" gasses. Carbon dioxide is one of these trace gases, and accounts for about 0.039% percent of air by volume. If we assume for a moment that we're at sea level, then the total pressure, by definition, is 1 Atmosphere (atm). This means that the partial pressure of nitrogen in air at sea level is .79. Oxygen is .21. Carbon dioxide is .00039. Every 33 feet a diver descends in sea water adds one additional Atmosphere to the Total Pressure. This means that Total Pressure at 33 feet is 2atm and at 66 feet is 3atm. PPO2 (partial pressure of oxygen) at 33 feet is .42. PPN (nitrogen) is 1.58. PPCO2 (carbon dioxide) is .00078. At 66 feet of sea water PPCO2 is .00117 (.00039 X 3atm).
Why there is a danger of bursting the lungs in Scuba diving?
Imagine filling a balloon with 1 litre of air at the surface of the ocean (1 atmosphere of pressure).At 10msw (metres of saltwater) of depth the pressure is double that of the surface (2atm) and the volume of the balloon will be halved.The actual amount of air has not halved just the space it takes up.The density of the air at 10m is two times the density of the air at the surface.If we go to 20msw the pressure is 3atm and the volume will be 1/3 of the surface volume and the air will be 3 times as dense etc ....Now imagine the opposite.We Fill a balloon at 10msw with 1 litre of the air that is 2 times as dense.We take this balloon to the surface.The air in the balloon will have expanded to double the starting volume as the pressure halved (2atm to 1atm) and the density will be half what it was at the start.Balloons have a reasonable capacity for expanding .... lungs don't. So if a scuba diver takes a breath of air at depth and then ascends the air will expand and, if the diver is not breathing out, will cause damage and possibly bursting of the lungs.
How do you calculate room pressure?
Pressure altitude can be determined by dialing your kollsman window to 29.92" or 1013mb the altitude displayed will be pressure altitude. Or if you want to use a mathematical equation to calculate pressure it is: 29.92-current baro.=x then take x*1000+Current field elevation=pressure altitude. Example: Current baro is 30.08 field elevation is 845'. 29.92-30.08= -.16 now take -.16*1000+845=685 is your pressure altitude.
How deep can scuba divers can?
I'm not sure how much is the deepest anyone's ever gone but there is a dive master at my Scuba place who has literally been over 400 feet!!! That's crazy! 318.25 meters without rope stretch by a portuguese guy called Nuno Gomes. That's 1044 feet and that's also the world record. To go below or to reach 400 feet depths technical diving training is needed. I am a dive master and i can only dive to the recreational diving limit that is 40 metres. anything below that is technical diving. diving that deep for fun is not heroic, its stupid.
