Question

A water storage tank is 5.0 m deep, and has a radius of 2.0 m. It is filled to the very top with water. (Assume normal atmospheric pressure)

What is the gauge pressure at the bottom of the tank?

[Do NOT include units in your answer. Provide a numerical answer only for this question. Do NOT use scientific notation for this answer.]

What are the proper units for the answers to the previous questions.

If a small hole (radius 2.0 mm) is punctured into the tank (described in the first part of the question) at a distance of 0.75 m above its base, at what rate will water flow out of this hole? (In other words, what is the speed of the water as it leaves the hole? Do NOT calculate the volume rate of flow.) [Do NOT include units in your answer.

Explanation / Answer

pressure at bottom=101000pascal+(998*9.81*5)

=149951.9 pascals

pressure absolute=pressure gauge+pressure atmosphere

units will be m/sec
