A horizontal segment of pipe tapers from a cross sectional area of 50 cm2 to 0.5 cm2. The pressure at the larger end of the pipe is 1.34 105 Pa and the speed is 0.038 m/s. What is the pressure at the narrow end of the segment?

Question

A horizontal segment of pipe tapers from a cross sectional area of 50 cm2 to 0.5 cm2. The pressure at the larger end of the pipe is 1.34  105 Pa and the speed is 0.038 m/s. What is the pressure at the narrow end of the segment?

drwls · Answer

The continuity equation
Area*velocity = constant
will tell you the speed at the smaller end.

Use the Bernoulli equation for the pressure difference due to velocity change.

If you need to review that equation, it should be in your text and is easy to find online.

Additional help will be provided when work is shown.
