A 50 lb bag of gravel typically covers about 0.5 cubic feet. To determine how many square feet it covers at a depth of 4 inches (which is 1/3 of a foot), you can use the formula: area = volume / depth. Therefore, a 50 lb bag of gravel would cover approximately 1.5 square feet at a depth of 4 inches.
3 atmospheres
Three atmospheres (3 ATM) of pressure is equivalent to a depth of approximately 30 meters (about 99 feet) underwater. This is because atmospheric pressure increases by about 1 ATM for every 10 meters of water depth. Therefore, at 3 ATM, you would be experiencing the pressure of three times the surface atmospheric pressure, which corresponds to that depth.
Rule of thumb is that each 33 feet adds an atmosphere of pressure. At sea level, 1 atmosphere, at 33 feet, 2 atmospheres, at 66 feet, 3 atmospheres, at 99 feet, 4 atmospheres, and at 132 feet, 5 atmospheres. A diver at 132 feet has 5 atmospheres of pressure on him.
ATM is the depth by which water resistance is measured on a watch. ATM stands for Atmospheres. 1 atmosphere is equivalent to appx. 33 feet depth in water. So if a watch is 3 ATM = 100 ft. water resistant.
The method is the same, but the formula differs depending on whether you want it in meters or feet. The easy method in feet is to add .3 atmospheres (ata) every 10 feet (or every 3 meters) and then add a surface atmosphere, so 30 feet would be: [(.3 x 3=.9) +1] = 1.9 ata The simple formula for feet is: (Depth + 33)/33 For meters it is: (Depth +10)/10 One atm is defined as 101.325 kPa or 14.7 psig. A somewhat newer unit has been introduced to replace atm, particularly when working in metric units. The "bar" is defined as exactly 100 kPa or 14.5 psig. One bar is equivalent to 32.81 feet of sea water.
The water pressure at 3 kilometers depth is roughly 300 atmospheres, which is equivalent to around 4400 pounds per square inch (psi). At this depth, the weight of the water above creates significant pressure due to gravity.
