Question

water is flowing in a cylindrical pipe of varying circular 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 thecwater at this point if the volume flow rate in the pipe is 1.20 m^3/s ?

b. at a second point in the pipe the water spped is 3.80 m/s What is the radius of the pipe at this point?

A large pipe with a cross sectional area A1=1.2 m2 has water flowing through it. The pressure in the pipe there is maintained at atmospheric pressure. The pipe then descends 3.7 m and narrows to a new cross sectional area A2. Water exits the pipe there into an environment at atmospheric pressure. What must the cross sectional area A2 of the pipe be in m2 if the water is exiting the pipe with a speed of 9.8 m/s?
