Question:
A jet of air from a nozzle is blown at right angles against a wall in which two pressure taps are located. A manometer connected to the tap directly in front of the jet shows a head of \(25 \mathrm{~mm}\) of mercury above atmospheric. Determine the approximate speed of the air leaving the nozzle if it is at \(-10^{\circ} \mathrm{C}\) and \(200 \mathrm{kPa}\). At the second tap a manometer indicates a head of \(5 \mathrm{~mm}\) of mercury above atmospheric; what is the approximate speed of the air there?
