Problem 6: Energy Equation Demonstration
Recently we saw a laboratory apparatus demonstrate several aspects of the energy equation. As
you will recall, the cross-sectional area of the pipe varied from a maximum of 4.909×104 m² at
point A to 7.854x105 m² at point E (factor of 6.25 difference):

Part A
What is the smallest velocity at Point E (VE) that will cause cavitation? T = 20°C, and you may
assume the pressure at Point A (PA) is one Denver atmosphere, so PA = Patm = 85 kPa. Neglect
the piezometer connections - assume they do not exist. [m/s]
Part B
In reality, of course, we do have piezometer connections at points A-F. What happens in the real
apparatus when the discharge equals the result from Part A? (≤25 words)
3. A differential manometer is attached to two tanks, as shown in figure.
A) Calculate the difference in pressure of the two chamber
B) Calculate the absolute pressure at A if the chamber B is open to atmosphere
