To calculate the water flow rate, square the pipe's diameter, and then multiply that number by pi, .25 and the velocity of the water flow. For example, a pipe with a diameter of 3 inches, or .25 feet, and a water velocit... More »

As more and more gas enters a fuel tank, the distance between the liquid and the nozzle shrinks, and a small pipe next to the gas nozzle sinks into the rising fuel. At that point, the small pipe's air pressure is choked ... More »
