The figure below shows parts A and B of a glass tube.

The figure below shows parts A and B of a glass tube.

(i) State the part of the tube in which the pressure will be lowest when air is blown through the tube to from A to B
(ii) Compare the velocity of air at A and at B
(iii) What is the relationship between the velocity of the air and its pressure at any point along the tube AB

---

i).A
ii) Velocity of air at B is higher.
iii).velocity is inversely proportional to pressure /increase in velocity , lower pressure.
