How Do You Calculate Water Flow, Volume & Pressure?
You can calculate the flow rate, volume and pressure in a water tank using formulas from physics. Volume is the amount of space that an object takes up, and may be measured in liters, gallons, or cubic meters. Flow is the rate at which a certain volume of liquid passes through an opening; it may be measured in liters per second or gallons per minute. Pressure is the amount of force per square unit of area, and is measured in pounds per square inch (psi) or Newtons per square meter (pascals). Measure the width, length and height of the water in meters. Multiply the width, length and height to compute the volume in cubic meters. The formula is V = WLH, where V is the volume, W is the width, L is the length and H is the height. Convert cubic meters to liters by multiplying by 1,000. Convert cubic meters to gallons by multiplying by 264.17. Place an empty container below the faucet or release valve. Open the valve and use the stopwatch to time the water flow for 15 seconds.
