STEM Lessons for College Students

12.39 . Water is flowing in a pipe with a circular cross section but with varying cross-sectional area and at all points the water completely fills the pipe. (a) At one point in the pipe the radius is 0.150 m. What is the speed of the water at this point if water is flowing into this pipe at a steady rate of 1.20 m3>s? (b) At a second point in the pipe the water speed is 3.80 m>s. What is the radius of the pipe at this point?

I have not created a lesson for this question yet.

Please leave a comment below with specifics about the question, and I will make a detailed lesson on it as soon as possible. (I can usually have something up within a day.)

NEED IMMEDIATE HELP? Get the student solution manual here: University Physics Manual otherwise, I should be able to get a video lesson up within a day or so.
