Practice Questions

Question 1

For steady incompressible inviscid flow at the same elevation, what happens to the static pressure when the flow speed increases?

Question 2

In air with density $1.2\ \text{kg/m}^3$, two points are at the same height. If the speed changes from $20\ \text{m/s}$ to $40\ \text{m/s}$, what is $p_1-p_2$?

Question 3

A flow has static pressure $101300\ \text{Pa}$, density $1.2\ \text{kg/m}^3$, and speed $10\ \text{m/s}$. What is the stagnation pressure?

Question 4

Which equation is the basic Bernoulli relation for steady incompressible inviscid flow along a streamline?

Question 5

If the flow speed doubles while density stays constant, by what factor does the dynamic pressure $\frac{1}{2}\rho v^2$ change?
