Question 4

An interesting topic in fluid mechanics is Bernoulli's equation,which relates pressures and velocities of a fluid with the densityof rho at different heights, eq. 13.12. It has applications in theairspace. It can be used to measure flow speed in a pipe with adevice named the Venturi meter (see figure 13.34). If the crosssections are 21 cm2 and 13 cm2, and the height difference resultedfrom the pressure difference is 0.2 m, calculate the speed of theflow in the pipe, v1 . Give your answer to one decimal point. YourAnswer:Question 4 options:
