Through a refinery, fuel ethanol is flowing in a pipe at a velocity of 1.1 m/s and a pressure of 101300 Pa. The refinery needs the ethanol to be at a pressure of 2.5 atm (202600 Pa) on a lower level. How far must the pipe drop in height in order to achieve this pressure? Assume the velocity does not change. (Hint: Use the Bernoulli equation. The density of ethanol is 789 kg/m3 and gravity g is 9.8 m/s2. Pay attention to units!)
