A 0.8 m diameter tank is filled with water to a depth of 2.2 m and is open to the atmosphere at the top. The water drains through a 1.0 cm diameter pipe at the bottom; that pipe then joins a 1.5 cm diameter pipe open to the atmosphere, as shown in Fig. 18-53.

(a) Find the flow speed in the narrow section.
(b) What is the water height in the sealed vertical tube shown?
Hmm didn't keep the spaces darn ;\, basically the tank was on the left, 1 cm pipe stretches for a bit out of the bottom right of the tank, midway through that ascending is a similar diameter vacuum tube for part b, and then to the right of the 1 cm pipe, it basically turns into a 1.5 cm pipe as described in the problem.
