Question 4

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

(Fluid Mechanics; Euler's equation and Bernoulli equation) As I know, in order to derive Euler's equation from Naveri-Stokes equation, the additional conditions are 1)Incompressible and 2)Inviscid Then, in order to derive Bernoulli's equation from Euler's equation, what additional conditions are needed? As I thought, Euler's equation already meets the incompressible and invsicid condtion, so only "steady state" is the additional condition to derive Bernoulli equation from Euler's equation. Am I right? In addition, are both Navier-stokes equation and Euler's equation...
