Um... there are 1 psi (lb/in2) = 144 psf (lbf/ft2) , if by (lb ft) you meant pounnds per square foot. then there is 1/144 psi in 1 (lbf/ft2)
1 bar is 14.50377 PSI, so 2.8 bars is 40.610 PSI.
This depends on what your target pressure is. If the height of the pipe is H in feet, the pressure at the bottom of the pipe from the column of water is 0.036127292 * H * 12 where 0.036127292 is the density of water in lbs/in^3. Thus, if your initial water pressure is I, the pressure at H feet will be I - 0.036127292 * H * 12 So you will have Height | Pressure +--------- 0 ft | 40 psi 10 ft | 35 psi 20 ft | 31 psi 30 ft | 27 psi 40 ft | 23 psi 50 ft | 18 psi 60 ft | 14 psi 70 ft | 10 psi 80 ft | 5 psi 90 ft | 1 psi 100 ft | 0 psi One will be required above 90 ft. You'll probably want one above 40 ft. Derivations: eq means equals. This wiki eats equals signs.

Pound per Square Inch = PSI means 1pound in terms of pressure will be 1 psi.
Psi stands for pound per square inch. This system is used to measure pressure. 1 Psi is equal to 1 pound of force on an area of 1 square inch.
There is no mathematical conversion needed - 1 psi is equal to 1 psi. The terms "psig" and "psi" are often used interchangeably to refer to pounds per square inch of pressure. However, "psig" specifically denotes pressure relative to the local atmospheric pressure, while "psi" is an absolute measure.
A one foot liquid head of water will exert a force of 1.04167 psi. 27.7 inches of water = 1 psig... Mean and dirty 1foot=1/2psig
To lift one pound using air pressure, you need approximately 1 psi. This is based on the principle that 1 psi can lift about 1 pound per square inch of surface area. Therefore, if you have a larger surface area, you would need proportionally less psi to lift the same weight. For example, a surface area of 2 square inches would require only 0.5 psi to lift 1 pound.
About 2 1 pound per square inch = 2.0362... inches of mercury
Ft Lbs (Foot pounds) is a measure of force; where as pounds is a measure of weight. They are not comparable.
To convert a height of 33.11 feet to pressure in psi (pounds per square inch), you can use the formula that relates height in feet of water to pressure: 1 foot of water is approximately equal to 0.4335 psi. Therefore, 33.11 feet of water would be approximately 33.11 ft × 0.4335 psi/ft, which equals about 14.35 psi.
The pressure is only dependent on the height of water above the measuring point. 1 psi corresponds to a height of 2.3 ft, so 8 ft = 3.5 psi The pressure is only dependent on the height of water above the measuring point. 1 psi corresponds to a height of 2.3 ft, so 8 ft = 3.5 psi
It is a measure of pressure in the near obsolete system of measurement. PSI stands for pound force per square inch. 1 PSI = 6895 Pascal, approx.
Every 2.3077 feet of water in a column increases the water pressure at the bottom of the column by 1 pound per square inch.A 39 foot column of water with a pressure of 120 psi at the base will have a pressure exerted on its top surface of 103.1 psi.39 ft/ 2.3077 ft/1 psi = 16.9 psi ; 120 psi -16.9 psi = 103.1 psievery meter of water in a column increases the pressure at the base of the column by 0.1 kg./ sq. cm (or 1 kilopascal)A 12 meter column of water exerts a pressure at its base of 12 kPa. (or 1.2 kg/sq. cm)
6.9 kPa = 1 psi
