Volumn weight of H2O?I need to know what would be the Pounds Per Square Inch of a 25 foot pipe 1/2"Inside Diameter filled with water. The answer can be either in PSI or volumnweight less the weight of the pipe.

Best Answer: If you are talking hydrostatic pressure, it is simply the functionof the depth at which you are measuring. It is roughly .433 psi per foot. In otherwords. If the pipe is verticle and you are measuring the pressure at the bottom, itwould simply be 25 X .433. The volume weight has nothing to do with this.

Err.. i think your question is kind of unclear.

1. You can find the volume of the H20 byV = L x A ; where L = length of pipe, A = pi * D^2 / 4....

and the dimension in cubic inch

2. You can find the Weight of the H20 byW = V x Dwwhere, V from equation 1, Dw is water Density... 1000 kg/m3. you may need toconvert them)

3. Psi is the pressure that your question asking.-Atmospheric pressure is always 1 bar in general. Normally we don't take Atmo-spheric Pressure into consideration unless the allitude in difference of 1000 me-ter.-I cannot compute the Psi for you as i do not know your 25 foot of pipe is verti-cally or horizontally place.- If horizontally place, Psi will be approximitely to 0- If vetically placed, then the pressure, Psi will be depending on which point youwant to calculate. You may use the following equation,Pressure = P = Dw x G x HWhereby, P = Pressure in PsiDw = Density of WaterG = Gravity in Feet / Second^2H = Height in feet, distance from A to B wherebyPoint A is from the surface of the waterPoint B is any point that you wish to calculate butlogically it won't exceed 25 feet.

The standard formula for the hydrostatic pressure would be

p = rho .g . h

where rho is the water density, g is the acceleration of gravity, and h is theheight of the water column.

Water pressure is about 1 decibar per meter, or about 1 atmosphere per 30 feet.Thus your water pressure will be roughly 15 pounds per square inch (ie., one at-mosphere)

we first calculate the volume of water wich = L d / 4= 25*12 * *0.5 *0.5 / 4= 58.904 in

and while density of water = 0.036 127 292 lb/inthenmass of water = 58.904 * 0.036 127 292= 2.128 lb

we calculate the area of the pipe =Ld=25*12* 0.5 * = 471.24 inso Volumn weight =0.0045 lb/in
