Water is flowing in a straight horizontal pipe of variable cross section. Where the cross-sectional area of the pipe is 3.70·10-2 m2, the pressure is 8.10·105 Pa and the velocity is 0.660 m/s. In a constricted region where the area is 16.90·10-4 m2, what is the velocity?

Tries 0/15

What is the pressure (in Pa)? (Assume an ideal fluid)
