6. (0.5 pt.) Water flowing through a pipe has a volume flow rate of 0.1 1/s (104 m'/s). If the pipe has a cross-sectional area of 1 cm (104 m?), at what speed (in m/s) is the water moving through the pipe? 7. (0.5 pt.) Suppose a pipe (not necessarily the one in Question 6) has a constriction where the cross-sectional area is reduced by half. If the water is flowing at a speed of 2 m/s in the rest of the pipe, what is the flow speed (in m/s) as the water passes through the constriction
