Adoctor finds a partial blockage in a blood vessel. the flow speed in the region of the partial blockage is 5100 mm/hour. in a nearby vessel that is clear, the area is 0.51 mm2 . the blood flow speed, in mm/hr, in the clear region is 1200 mm/hr. what is the cross-section area, in mm2 , available for blood flow near the blockage

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

i already answered it by 34/s

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
