As Shown in the Figure,water (Density 1000 Kg $m ^ { 3 }$

Short Answer

As shown in the figure,water (density 1000 kg/ $m ^ { 3 }$ )is flowing in a pipeline.At point 1 the water speed is $5.90 \mathrm {~m} / \mathrm { s }$ Point 2 is 5.20 m above point 1.The cross-sectional area of the pipe is 0.0800 $m ^ { 2 }$ at point 1 and $0.0200 \mathrm {~m} ^ { 2 }$ at point 2.What is the pressure difference $p 1 - p 2$ between points 1 and 2? Treat the water as an ideal incompressible fluid.
