According to equation of continuity,
According to equation of continuity,
Show Hint
When flow area decreases ($a_2 < a_1$), velocity must increase ($v_2 > v_1$) to keep volumetric flow rate constant.
This simple principle explains how nozzles work.

- $w_1 a_1 = w_2 a_2$
- $w_1 v_1 = w_2 v_2$
- $a_1 v_1 = a_2 v_2$
- $a_1/v_1 = a_2/v_2$
Show Solution
The Correct Option is C

A pitot tube connected to a U-tube mercury manometer measures the speed of air flowing in the wind tunnel as shown in the figure below. The density of air is 1.23 kg m\(^{-3}\) while the density of water is 1000 kg m\(^{-3}\). For the manometer reading of \( h = 30 \) mm of mercury, the speed of air in the wind tunnel is _________ m s\(^{-1}\) (rounded off to 1 decimal place).
