MM301 FLUID MECHANICS

Problem Set 3

1) 3.48 A 50-mm-diameter plastic tube is used to siphon

water from the large tank shown in Fig. P3.48. If the

pressure on the outside of the tube is more than 30

kPa greater than the pressure within the tube, the

tube will collapse and the siphon will stop. If viscous

effects are negligible, determine the minimum value

of h allowed without the siphon stopping.

2) 3.52 Water flows steadily downward through the

pipe shown in Fig. P3.52. Viscous effects are

negligible, and the pressure gage indicates the

pressure is zero at point (1). Determine the flow rate

and the pressure at point (2).
