Upstream Gage Pressure Across Pipe Transition
A piping system conveys water under pressure across a pipe reduction and increase in elevation. The gage pressure downstream, gage 1, reads 75 KPa. The velocity just downstream of gage 1 is 5.0 m/s. If pipe diameter one is 6 cm and pipe diameter two is 4 cm, what does gage 2 read in KPa given that the increase in elevation is 2.0 m? Take: g=9.81 m/s^2, atmospheric pressure is 101, 325 Pa, and the density of water is 997 Kg/m^3. Provide your answer to the nearest 1/10th.
The answer is 4.8.
