Question 1129643: Water is flowing through a pipe at a speed of 2.7 m/s (labelled as v1 below). The pipe has a cross-sectional area of 0.02 m2. It then splits so that it flows through two identical pipes, each of which has a cross-sectional area of 0.038 m2. At what speed (in m/s) does the water flow through the larger pipes?
Hint: Don't let the fact that there are two pipes confuse you: think about what the 'effective' area is through which the water is now flowing. Use the continuity equation for incompressible fluids.

Question 1130096: Question regarding the below example.
E and F are mutually exclusive and P(E) = 0.2 and P(F) = 0.5. Find P(E
U F).
If the two are mutually exclusive, using the addition rule, wouldn't P(E U F)=0.7? This is just a guess on my part as I don't know how to work through this type of problem.
Can someone please provide an explanation?
Thank you!
