As shown in the diagram, a T-shaped straw is dipped into a glass of water.
If you blow air through the opening on the left, leaving the opening on the right open, what will happen?
Details and Assumptions:
- The incoming air flow is V˙=0.5l/s.
- The straw with diameter 6mm has a length of 8cm, half of which is immersed in the water.
- The densities of air and water are ρ=1.2kg/m3 and 1000kg/m3, respectively.
- The viscosity of air is neglected so that there is no pressure drop along the pipes.
