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 cm^2 and after a few meters the presence of debris creates a constriction reducing the pipe cross sectional area to 250 cm^2. You are able to check the water speed at the 450 cm^2 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?
