![]() ![]() Therefore, to find the feet head of water for any pressure. = 703. NOTE: One Pound of pressure per square inch of water equals 2.31 feet of water at 60 Fahrenheit. Psi to Pound-force/square Foot Conversion Table How to Convert Psi to Pound-force/square. = 0.06804596391019 atmosphere atm standard (atm) Therefore, the pressure of 1 inch of water in a water column is 0. On that same note, 1 pound per square inch can produce 2. In relation to the base unit of => (pascals), 1 Psi (psi) is equal to 6894.7572932 pascals, while 1 Foot Of Water (ftH2o) = 2988.98 pascals. Table 3.1 indicates that 1 foot of water head or lift produces 0.5 pounds per square inch of pressure. How to Convert Psi to Pound-force/square Foot. How to convert Psi to Foot Of Water (psi to ftH2o)?ġ x 2.3067258038528 ftH2o = 2.3067258038528 Foot Of Water.Īlways check the results rounding errors may occur. As a result, you would feel the same water pressure if you were in these containers of the same height.The base unit for pressure is pascals (Non-SI Unit) But remember that the cone is also supporting some weight of the water! The surface of the cone is facing upward while the wall of the test tube is vertical and cannot support any water. This may be a little counter-intuitive because there is more water in a giant ice cream cone than a giant test tube. You mentioned an important point that water pressure is the same at the same depth, regardless of the shape of the container. For example, we can measure how much force is exerted by water and divide it by the area of the detector. The presence of water pressure does not require air, so we can measure pressure directly under water. Definition: In relation to the base unit of pressure > (pascals), 1 Psi (psi) is equal to 6894.7572932 pascals, while 1 Foot Of Mercury (ftHg. Always check the results rounding errors may occur. In water (or air), the weight of the water (or air) above you exerts a force on you, so you feel water pressure (or atmospheric pressure). How to convert Psi to Foot Of Mercury (psi to ftHg) 1 psi 0.16966840515928 ftHg. For example, when you press a button, you are putting pressure on it. ![]() Every force that acts on a surface corresponds to a pressure. Pressure is how much force you feel per unit area. Since specific gravity is a ratio of the weight of a liquid compared to the weight of water, the specific gravity of a liquid such as 28 nitrogen fertilizer, which weighs 10. To get to 29.4 psi, it turns out that you would need to be 33 feet deep. Water weighs 8.34 lbs./gallon and has a specific gravity of 1. In order to get to 2 atmospheres worth of air pressure, you would need to get to the point where there’s 29.4 psi (2 times 14.7 psi). And at two feet deep it would be 14.7 psi + 2*(0.445 psi) = 15.59 psi, etc. would exert a maximum hydrostatic head pressure of 20 feet of water column. So at one foot deep, the pressure would be 14.7 psi + 0.445 psi = 15.145 psi. 1 inch of water column 0.03613 PSI (27.678 inches of water column 1 PSI). Reminder: It doesnt matter what the area. And for every foot you go underwater, you add another 0.445 psi. We already calculated that having a column of water one foot in height gives us 0.433 psi at the base of that column. So if you’re right at sea level, the pressure will be 14.7 psi. Each one inch column that’s one foot deep will weigh 0.445 pounds. For this reason, we like to say that the standard air pressure (at sea level) is 14.7 pounds per square inch (psi). ![]() If we were to take a one inch column of air all the way up through the atmosphere, it would weigh 14.7 pounds. First, we have to understand how pressure is measured. Well, let’s see if we can work this one out. ![]()
