Problem 2 Through a refinery, fuel ethanol is flowing in a pipe at a velocity of 1 m/s and a pressure of 101300 Pa. The refinery needs the ethanol to be at a pressure of 2 atmi (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!)

Problem 1
Water is flowing in a fire hose with a velocity of 1.0 m/s and a pressure of 200000 Pa.
At the nozzle the pressure decreases to atmospheric pressure (101300 Pa), there is
no change in height. Use the Bernoulli equation to calculate the velocity of the water
exiting the nozzle. (Hint: The density of water is 1000 kg/m3 and gravity g is 9.8 m/s-.
Pay attention to units!)]
Problem 2
Through a refinery, fuel ethanol is flowing in a pipe at a velocity of 1 m/s and a pressure
of 101300 Pa. The refinery needs the ethanol to be at a pressure of 2 atmı (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!)
Summary
Pascal's law states that a change in pressure at any point in an enciosed fluid
is transmitted equally throughout the fluid. The ability of fluids to transmit pressure
in this way can be very useful-from getting toothpaste out of a tube to applying
