5. A Pitot-static probe connected to a differential pressure gage is used to measure the air velocity in a duct. If the air is at 13.4 psia absolute and 70°F and the reading of the differential pressure gage is 0.15 psi, determine the air velocity. Ans. 143 ft/s 6. A fabricated assembly made from three different sizes of standard steel tubing is shown below. The larger tube on the left carries 0.072 m3/s of water. The tee branches into two smaller sections. If the velocity in the 50-mm tube is 12.0 m/s, what is the velocity in the 100-mm tube? Ans. 7.88 m/s Flow 160-mm OD x 5.5-mm wall steel tube Reducing tee 100-mm OD x 3.5-mm wall steel tube 50-mm OD x 15-mm wall steel tube
