level. determine the owrate as a function'of the diameter of
the small pipe, D.

strikes a curved vane, which is in a vertical plane as shown in
Fig. P5. 62. A stagnation tube connected to a water U-tube
manometer is located in the free air jet. Determine the horizontal
7.65' The pressure rise, Ap, across a centrifugal pump of a
given shape (see Fig. P7.65a) can be expressed as 8
AP = f(D. w. p. Q)
where D is the impeller diameter, a) the angular velocity of the
impeller, p the uid density, and Q the volume rate of ow
5.10 Water enters a cylindrical tank through
two pipes at rates of 250 and 100 gal/min (see
Fig. P510). If the level of the water in the tank
remains constant, calculate the average velocity Section (2)
of the ow leaving the tank through an 8-in.-

As shown in Video V1.2, the no slip" condition
means that a uid sticks to a solid surface. This is true for
both xed and moving surfaces. Let two layers of uid be
dragged along by the motion of an upper plate as shown in Fig.

Demonstration: A candle is lit and the shape of the luminous flame is observed. The
candle is then extinguished and the character of the rising smoke plume is examined.
Observation: When the candle flame is extinguished, at firs
