# How much does water pressure increase per vertical foot?

# How much does sea water weigh per cubic foot?

The weight of sea water really depends on a number of variables, including the temperature, the amount of salt (salinity) and whatever other foreign items may be present, and …the depth, thus the pressure. But to get to the basic answer, seawater, at the surface, on average weighs 1027 kg/m3, or just over 64.1 lbs per cubic foot. ----------- The question is another way of asking for density of salt water. Salt water has greater density than that of fresh water, due to the dissolved salt. Fresh water has a density of 1000 kg/cubic meter vs. an average density of 1027 kg/cubic meter for ocean salt water.

# How much pressure does a 10-foot vertical pipe filled with water put on the cemented joints of a newly laid sewer line?

Every foot of water (i.e. foot of head) equals 2.31 psi (i.e. pounds per square inch). answer I think that first answer is backwards. It takes 2.31 vertical feet of pipe to… create 1# of pressure. Stated another way, one foot vertical equals roughly .434 psi. When a plumber tests the underground with a ten-foot stack, approximately 5 pounds pressure is applied. That is why some codes allow a 5 pound air test in lieu of water in cold weather and in other situations where it is more practical.

# How much does fresh water weigh per cubic foot?

\n.
\n Weight of Fresh Water \n.
\n1cu ft = 12 * 12 * 12 cu.in = 1728 cu in = 1728 * (2.54*2.54*2.54) cc = 28316.85 cc = 28.3 liters = 28 kg or 62.4 pounds

# How much PSI does it take to move water one vertical foot?

Answer .
\n.
\nThe pressure at the bottom of a column of fluid is (rho)gh, where \nrho is the density of the fluid\ng is the acceleration due to gravity (9.8 m/s2 or 32.2 …ft/s2)\nh is the height of the column\n.
\nWater has a density of about 56 pounds-mass per cubic foot,\nso a 1 foot high column has a pressure at the bottom of \n.
\n62 lbm/ft3 * 32.2 ft/s2 * 1 ft = 1803 lbm/ft-s2.\n.
\nThe magic conversion constant is 1 lbf-s2/32.2 lbm-ft and\nwe could have saved some trouble by doing it up front\n62 lbm/ft3 * 32.2 ft/s2 * 1 ft * 1 lbf-s2/32.2 lbm-ft = 62 lbf/ft2\nIf we divide this by 144, we get 0.43 psi.\n.
\nI never trust calculations in English units, so\nThe density of water is 1000 kg/m3, so the pressure at the bottom of \na 0.305 m tall column of water is \n1000 kg/m3 * 9.8 N/kg * 0.305 m = 2989 Pa.\n.
\nSince 1 atmosphere = 14.696 psi = 101325 Pa, the pressure at the\nbottom of your column is \n2989 Pa * 14.696 psi/101325 Pa = about 0.43 psi.\n.
\nNow that I think of it, we could have multiplied the first equation \nby

# How much pressure per square inch is on the human foot when walking?

Answer .
If it is smooth walking where no additional forces are added except for the shift in body weight, and if the average person weighs 150 lbs and has an average surfa…ce area on one foot of 25 square inches, then each square inch would support about 6 pounds per square inch. That is when all the body weight is shifted onto one foot at a time. This doesn't actually happen this way when we walk, but this may give you a general idea of the forces involved.

# How much pressure is needed to raise water one foot?

This question is misguided. You don't need pressure, you need energy. Energy = work done = mass of water x g (acceleration due to gravity) x height raised. Pressure = forc…e/area over which it is applied (e.g. the cross section of the water pipe.) So the pressure needed is given by P = mgh/area Be sure your value of g is in the right units for your mass and height measurements. Differential air pressure will be shown by raising the water level in, for example, a U shaped tube, where differentail pressure is applied between the two arms. Yes, to move the water, energy is used. BTW, energy equals force (weight) times distance, but you are not lifting all the water by one foot.

# How much pressure per square inch is on human foot when going down stairs?

You can't say 'pressure per square inch. It's just 'pressure',which equals force per square inch. You divide the person's weightby the area of the foot in contact with the sta…irs to get theanswer.
