Question:

You need to siphon water from a clogged sink. The sink has an area of 0.48m2 and is filled to a height of 4.0cm. Your siphon tube rises 50 cm above the bottom of the sink and then descends 100cm to a pail as shown in Fig. 10-58. The siphon tube has a diameter of 2.0 cm.
(a) Assuming that the water enters the siphon tube with almost zero velocity, calculate its velocity when it enters the pail
(b) Estimate how long it will take to empty the sink.
