Unformatted text preview: 4. Consider a cylinder of radius r and length L ≫ r , and with uniform density less than water. You place the cylinder in water. It ﬂoats, with part of it’s volume out of the water. Depending on the density of the cylinder, it will ﬂoat either with it’s long axis vertical, or horizontal. Find the condition the density must satisfy in the two situations. 5. (Knight, Question 24, page 471). A 1.0cmdiameter pipe widens to 2.0 cm, then narrows to 5.0 mm. Liquid ﬂows through the ﬁrst segment at a speed of 4.0 m/s. (a) What is the speed in the second and third segments? (b) What is the volume ﬂow rate through the pipe?...
