It depends on the tank. The 20 oz is what the CO2 weights, but each tanks is slightly different, which is why CO2 tanks must be weighed.
Depending on the size, anywhere from 9 oz to 24 oz of actual CO2 inside. the tank itself weighs significantly more.
any co2 tank will have an output pressure around 800 psi or 57 kg/cm2
Every tank is slightly different, which is why an accurate scale is needed for proper CO2 filling.
Slightly under 50 pounds.
Around 4 pounds
Formula: kg/cm2 x 9.807 = newtons/cm2
I would not expect to see any CO2 bubbles in any aquarium I had set up. In a properly planted tank with good lighting and water parameters there should be no need to add extra CO2. Anyways, I have added CO2 in my tank. Now please tell me how many bubbles per minute? All the info you require can be found here http://www.brainyday.com/jared/aquarium/co2.htm
400ppm
Multiply x .12 to get cm2 or by 1.2 to get the m2
1 MPa = 10 kg/cm2 (MPa is pressure, kg/cm2 is mass/area not actual pressure)
If we multiply the cross sectional area of the trough by the speed of the water in the trough, we get the volume of water per second that is running into the tank. 18 cm2 x 3 meters/sec = 18 cm2 x 300 cm/sec = 5400 cm3 /sec As 1 cm3 = 1 ml, the tank is filling at a rat of 5400 ml/sec or 5.4 liters/sec
(1.08W/cm2)(10-3kW/W)(104cm2/m2)=10.8W/m2.
6.5 grams CO2 divided by 44 grams CO2 per mole CO2 = 6.8 mole CO2 (Molar mass CO2 = 12 + 2*16 = 44 g/mol)
1 kilo pascal = 0.01019716 kg/cm2
I have read it some where that the inside pressure of Co2 in fire extinguisher is 55 to 58 kg/cm2 at 21 deg C. However the pressure varies as per the ambient temperature.
Need to know how many gallons the fuel tank holds and how many miles per gallon the vehicle gets.
5000 people per year.
