Atank contained 35 gallons of water at first. due to leak at the bottom of the tank, the amount of water in the tank decreased to 32 gallons after 1 hour. after another hour, the amount of water in the tank was 26 gallons. a) find the percent decrease in the amount of water from 35 gallons to 32 gallons. round your answer to 1 decimal place. b) find the percent decrease in the amount of water from 32 gallons to 26 gallons. round your answer to 1 decimal place

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?
