A student needs to calculate the water flow rate through a pipe with a diameter of 5 cm, using Bernoulli's principle. The pipe is connected to a water tank which is 1 meter above the ground and has a pressure of 2 atm. The pipe exits at a height of 50 cm from the ground and is connected to a sprinkler. The sprinkler is located at a distance of 10 meters from the tank and is installed at a height of 1 meter from the ground. Calculate the water flow rate through the pipe, assuming that the sprinkler operates at atmospheric pressure.
