QUESTION
At a certain point in a horizontal pipeline, the water's speed is 2.50 m/s and the gauge pressure is 1.7010^4 Pa.
At a certain point in a horizontal pipeline, the water's speed is 2.50 m/s and the gauge pressure is 1.70×10^4 Pa. Find the gauge pressure at a second point in the line if the cross-sectional area at the second point is twice that at the first.
