30ft rise = 13 psi (pressure is 13 psi higher at bottom of a 30ft column that at the top). Water Pressure = .433 psi per ft for a column of water at 62 degrees F.
In most there is a washer in them that has a small hole in it so that only so much water can get through regardless of how much pressure is behind it.
10 feet x 0.433 psi/ft = 4.33 psi at the base of the cylinder.
For every 10meter head there will be one kg/cm2 drop in pressure when the head is 30meter above then the required pressure should always be more than the head, if the pump is used only for filling the storage tank you need not go for much higher pressure pump that would make your operating cost high. It would be better if you opt for around 4 kg/cm2 pump provided your take into consideration the number of bends used in the piping and the amount of pressure dropped in the bends.
300mm is a very low head, you can't expect much flow through that pipe, but you can work it out from the mechanical energy balance equation.
4,000 PSI working pressure
A pressure treated 6x6 usually weighs around 3.2 pounds per linear foot.
about 2 psi. (0.5 psi / foot of depth)
The FINAL torque value should be 78 foot-pounds, but the tightening process goes in 3 stages. I don't recall off the top of my head just what the torque values are for the first and second stages.
64.30
To calculate the head force required to create 1 psi (pound per square inch) of pressure, you can use the formula: Head Force (lbs) = Pressure (psi) x Area (in2). The actual value of the head force will depend on the specific area over which the pressure is being applied.
20 foot pounds
fibula tibula
approximately 12 psi when standing on all fours
An inch is a unit of length. A foot pound is a unit of pressure. The two units are therefore incompatible.
In a auto its how hard you push your foot on the peddel or on a motocycle how much twist on your wrist haha
A standard cubic foot of methane at room temperature and pressure weighs about 0.0419 pounds, or 18.9 grams.
You can't say 'pressure per square inch. It's just 'pressure', which equals force per square inch. You divide the person's weight by the area of the foot in contact with the stairs to get the answer.
