Let's consider in this question that blood flow in the coronary arteries is ideal. The left main coronary artery $($LMCA$)$ is blocked so its radius is decreased by $90\%.$ Find the pressure difference between the clogged part of the artery compared to the unclogged part, that is$,$ find p$\_($clogged $)-$p$\_($unclogged $).$ Assume that the artery is horizontal, velocity of the blood in the unclogged part is $0\mathrm{.}1($m$)/($s$),$ and density of blood is $1000(($kg$))/($m$^(3)).$

A$.+49,995$ Pa

B$.-98,675$ Pa

C$.-49,995$ Pa

D$.+25,671$ Pa

E$.+98,675$ Pa
