Use this information for questions 21 and 22. A fluid flows at 0.252 m/s through a pipe with a circular cross-section and diameter of 44 mm. The pipe widens to a square cross-section that is 5.5 cm on a side. What is the speed of the fluid through the square section? 0.506 m/s 0.127 m/s 0.00302 m/s 0.0403 m/s   If the pipe remains at the same level, which section, circular or square, has the greater pressure? Circular Square They are the same Unable to determine

Water flows through a pipe that gradually descends from a height of 6.78 m to the ground. Near the top, the cross-sectional area is 0.4 m2, and the pipe gradually widens so that its area near the ground is 0.8 m2. Water leaves the pipe at a speed of 16.8 m/s. What is the difference in the water pressure between the top and bottom of the pipe? Pa

Water flows in a pipe as shown in the picture. At point A, the pipe diameter is 18 cm and the speed of the water is 8.0 cm/s. At point B, the pipe diameter is 9 cm. What is the speed of the water at point B. A 16 cm/s 2.0 cm/s 4.0 cm/s 8.0 cm/s 32 cm/s

Air flows through the tube shown in the figure at a rate of 1200cm^3/s . Assume that air is an ideal fluid.  Assume that air is an ideal fluid.  P mercury = 13,600 kg/m^3 and P air = 1.40 kg/m^3. a. What is the air velocity in the 2cm diameter pipe in m/s. b.  What is the air velocity in the 4.0 mm diameter pipe in m/s. c.  what is the hight of the mercury on the right side of the U-tube in cm?
