Answer:

Step-by-step explanation:
= flow speed in the region of the partial blockage = 5100 mm/h
= flow speed in the clear region of nearby vessel = 1200 mm/h
= Cross-sectional area for the clear region = 0.51 mm²
= Cross-sectional area for the region near the blockage
According to equation of continuity, Volume flow rate must remain same at all points. hence
