How do scuba divers sink if they have tanks of compressed air on their backs?
The average aluminum SCUBA cylinder holds 80 cubic feet of air at pressure. That means you are taking the equivalent of a closet's worth of air and smashing it into a cylinder much smaller than that. When full, the cylinder is at 3,000 pounds per square inch of pressure.When the valve is opened, it sends air into the (assumed) first stage regulator which is connected by hoses to gear such as two second stage regulators, instruments and your vest.So the SCUBA tanks don't so much USE the air so much as STORE the air at high pressures.
How much water can the air hold when the relative humidity of the air is 25?
how much water vapor can a cubic meter of air hold at 25 centigrades grades?
Why relative humidity increases as temperature decreases and vice versa?
"Relative" humidity means how much water vapor there is in the air compared tohow much the air could hold at that temperature.And warmer air can hold more water vapor. Cooler air can hold less.So ... if there's a certain amount of water vapor in the air, and the air temperaturedrops, the air can now hold less at the reduced temperature, so the amount that'sthere is now a greater fraction of how much the air could hold ... higher relativehumidity.See the link below for the formula of Buck; the effect of temperature is evident.
Amount of moisture in air compared to amount needed in saturation?
Relative humidity is a measure of how much moisture is in the air compared to how much moisture the air can hold at a given temperature. If the relative humidity is 100%, the air is saturated and can hold no more moisture. Lower relative humidity means the air is drier and can still hold more moisture.
Can hot air or cold air hold more water?
warm air hold more water vapor...unless it doesnt like sandwiches between its toes at 5 o'clock in the after noon
Can a dolphin breathe in and out of air and water?
Dolphins are mammals. They breathe air with lungs, pretty much just like you and I. They can't breathe water. When they dive they hold their breath.
If the air you breathe is 80 nitrogen 20 oxygen what the ratio in a dive cylinder?
In a typical scuba diving cylinder, the air mixture is compressed and stored. The ratio of nitrogen to oxygen in the dive cylinder will be the same as atmospheric air, around 78% nitrogen and 21% oxygen. However, very specialized mixes may be used depending on the dive plan.
How much air in a cylinder?
Depends on the size of the cylinder, if the air is compressed or not and if it is compressed, to how much psi.
How long can american crocodiles breathe under water?
Crocs don't breathe underwater. They have lungs and Breathe air pretty much just like you and I. They hold their breath when they dive.
How does a green sea turtle breathe?
They breathe air through their nostrils. They simply hold their breath when they need to dive.
How much deep can a crocodile dive?

How much air can a ACU hold?

How much water can the air hold when the relative humidity of the air is 25?

What is the volume of air while scuba diving for 30 min?
there is no way to answer this question. (assuming) you mean volume of air used during a 30 minute dive the amount is dependent upon the depth of the dive. for future reference you CAN calculate how much air you would use on a specific dive by knowing and calculating your SAC (Surface Air Consumption) rate.
How do you do the dolphin dive on xbox black ops?
u run and jump and as soon as u get up in the air hold down the x button
