Chapter 11, Problem 069
A Venturi meter is a device for measuring the speed of a uid within a pipe. The drawing shows a gas lowing at speed vy through a hortrontal section of pipe whose cross-sectionel arma is A
0.0602 m. The gas has a density of p- 1.30 kg/m. The Venturt meter has a cross-sectional area of A0.0169 m and has been substituted for a section of the larger pipe. The pres
difference between the two sections is P- P-68.7 Pa. Pind (a) the speed vy of the gas in the larger original pipe and (b) the volume flow rate Q of the ges.

The aorta pumps blood away from the heart at about 40 cm/scm/s and has a radius of about 1.0 cmcm.It then branches into many capillaries, each with a radius of about 5××10−4−4 cmcm carrying blood at a speed of 0.10 cm/s
How many capillaries are there?
Two valves, one on top and one on the side, must be closed at the same time on an oil-field pump. The valve wheels have a diameter of 27 inches and are rotated with both hands by personnel who can apply 45 to 120 pounds of force with each hand. What is the total couple moment (lb-inch) and direction (clockwise) on the pump if a weak worker turns the side wheel and a strong worker rotates the top wheel?
