If the pressure (psi) is known, The height of the water column can be determined by multiplying the psi by 2.31. psi X 2.31 = Feet of Head Example: 1. A pressure gauge at the bottom of a storage tank reads 30 psi. What is the water level in the tank? A. Convert psi to feet of head 30 psi x 2.31 = 69.3 feet of water above the gaugeIf the height of a column of water is known, the pressure itexerts can be determined by dividing the feet of head by 2.31. Feet of Head = psi 2.31 Example: 2. The reservoir level is 115 feet above the pump discharge. What is the discharge pressure on the pump?
all you have to do is divide... 32/35=0.914. You multiply that by 100, and get 91.4%. So, there is still 91.4% of the water remaining in the tank, meaning that by using subtraction (100-91.4), we find that after one hour, 8.6% of the water has drained. Doing the same thing for number 2, 26/32=0.8125. Using our basic knowledge of rounding, we multiply this number by 100, and concur that there is 81.2% of the water remaining in the tank at this point. Using subtraction, (91.4-81.2), we find that 10.2% of the water drained in the second hour. Over the two hours combined, 18.8% of the tank's water has drained.
