question 81

Short Answer

As shown in the figure, water $\text { (density } 1000 \mathrm {~kg} / \mathrm { m } ^ { 3 } \text { ) }$ is flowing in a pipeline. At point 1 the water speed is 5.90 m/s. Point 2 is 5.20 m above point 1. The cross-sectional area of the pipe is $0.0800 \mathrm {~m} ^ { 2 }$ 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.
