Water flows in a horizontal pipe of length l. at the midpoint l/2, the pipe diameter changes. on one side of the midpoint, the pipe diameter is 8 cm, and the water is flowing at 0.5 m/s. on the other side, the water is moving at 2 m/s. what is the second diameter of the pipe?

4cm

Explanation:

Hello!

To solve this problem use the following steps, the procedure is attached.

1. draw the complete outline of the problem

2. Use the continuation equation that states that the volumetric flow at the inlet of the pipe is the same as it should come out, remember that the flow is the product of the cross-sectional area by the flow rate, finally use algebra and input data to Find the exit diameter.

answer; i believe the correct answer is (40,000 j) good luck
