Given the viscosity is negligible atmospheric pressure is, Ask an Expert

Academics

Given: The viscosity is negligible. Atmospheric pressure is 101300 Pa.

Water flows at speed of 4.9 m/s through a horizontal pipe of diameter 3.2 cm. The gauge pressure P1 of the water in the pipe is 1.5 atm. A short segment of the pipe is constricted to a smaller diameter 2.2 cm.

What is the speed v2 of the water flowing through the constricted segment in m/s?

What is the gauge pressure of the water flowing through the constricted segment in atm?
