Question: You are asked to test an underground pipe with clean water steadily flowing through. The pipe starts with a large cross sectional area of 450 cm2 and after few meters the presence of debris creates a constriction reducing the pipe cross sectional area to 250 cm2. You are able to check the water speed at the 450 cm2 area and you measure 5 m/s. Assuming that the water flow is steady, what do you expect to be the water speed at the constriction?
