A horizontal tube consists of a pipe that narrows to a 2.0-cm-diameter throat. In the pipe, the water pressure is twice atmospheric pressure and the water flows with a speed of What is the pressure in the throat, assuming that the water behaves like an ideal fluid?

Complete Question:

A horizontal tube consists of a 7.0-cm-diameter pipe, that narrows to a 2.0-cm-diameter throat. In the pipe, the water pressure is twice atmospheric pressure and the water flows with a speed of 0.40 m/s. What is the pressure in the throat, assuming that the water behaves like an ideal fluid. The density of water is 1000 kg/m^3, and the atmospheric pressure is 1.01 x 10^5 Pa.

1.9 atm is the pressure in the throat

Explanation:

First find velocity of water and then find the pressure using Bernoulli's Principle.

c. magnitude and direction
