You are measuring the velocity of air at standard temperature and pressure in a
1” pipe. You initially estimate the velocity to be 50 ft/s, if the mass flow rate is
independent of the velocity in the section where you are making the
measurements
determine the extent a probe that can be considered a 1/4” tube
will disturb the velocity of the flow.

You will be measuring velocity with the Pitot tube. Assume that the air density is 1.18 ± 1 x 10-4 kg/m3 and that the pressure sensor measures a differential pressure of 29.4Pa ± 1.0% FS. (Sensor range 0-60 Pa) Determine the uncertainty in the velocity reading. (Hint: Calculate the expected velocity from the Pitot tube. Remember uncertainty theory when multiple variables are involved!)

The air in the driven section of a shock tube is initially at the temperature and pressure of 300 k and 0.1 atm. After the diaphragm is broken, an incident shock wave with a velocity of 1440 m/s is propagating into the driven section where a pitot tube is placed. The pitot tube is facing toward the oncoming incident shock wave With its axis parallel to the axis of the shock tube. calculate : a) the total pressure of the...

2 A paint sprayer pumps air through a constriction in a 0.025- m diameter pipe, as shown in the figure. The flow causes the pressure in the constricted area to drop and paint rises up the feed tube and enters the air stream. The speed of the air stream in the 0.025-m diameter sections is 5.00 m/s. The density of the air is 1.29 kg/m3, and the density of the paint is 1200 kg/m3. We can treat the...

Air flow is induced in an insulated tube of 7.16 mm diameter by a vacuum pump. Air is drawn from a room where stagnation pressure is 101 kPa (abs) and stagnation temperature 23 °C, through a smoothly contoured converging nozzle. At station (1), where the converging nozzle joins the constant area tube, the static pressure is 98.5 kPa (abs). At section (2), located some distance downstream in the constant area tube, the air temperature is 14 °C. Determine a) the...
