Proof Read;Physics Solution At a point in a pipe carrying a fluid, the diameter of the pipe is 5.0 cm and the average speed of the fluid is 10 cm/s. What is the average speed, in m/s, of the fluid at a point where the diameter is 2.0 cm?

    Since I already know the diameter of the original tube which is 5.0cm, The area of the circle is calculated by (3.14)(2.5)^2=19.625cm^2 On the other hand the area of the second tube where the diameter is decreased from 5.0cm to 2.cm the area is (3.14)(1.00)^2=3.14cm^2 Therefore assuming that equation of continuity holds true in this situation 10m/s*(19.625cm^2/3.1cm^2)=10m/s*6.330=63.30m/s^2 Adjusting for sig figs of 1, Therefore velocity of the water increased from 10m/s^2 to 60m/s^2 .

    Please see if my solution is well reasoned according to the principles of continuity equation. Thanks!

    In my honest opinion this line of reasoning seems pretty sound to me.

    Water behaves like air does... But some properties are so different that water is used as multiplier of force.

    no... I'm more geared towards the general computational math and pure math. So, anything to do with Science, I will run real fast . ^_^

    If you combine your brain and my brain it will be well balanced
