A 1 cm diameter plastic sphere falls in a viscous liquid at a terminal velocity of 1 cm/sec. What would be the terminal velocity of a 10 cm diameter sphere (of the same plastic material) in the samefluid? Clearly state any assumptions that you make to arrive at your answer
Speed measurement is made with a pitot tube by connecting a mercury manometer to a vertical pipeline through which water is transmitted. If the deviation in the manometer column is 15 cm, calculate the speed of the water in the pipe.?mercury = 13560 ???3, ?water = 1000 ???3 (figure in picture)

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)
