The platelets are drifting with the blood flowing in a streamline flow through a horizontal artery as shown below. The artery is contracted in region $II$. Choose the correct statement.
- AAs the platelets enter a constriction,the platelets get squeezed closer together in the narrow region and hence the fluid pressure must rise there.
- BAs the platelets enter a constriction,pressure is lower there.
- CThe artery's cross-section area is smaller in the constriction and thus the pressure must be larger there because pressure equals the force divided by area.
- DPressure is same in all the parts of the artery.

View SolutionWater is in streamline flow along a horizontal pipe with non-uniform cross-section. At a point in the pipe where the area of cross-section is $10 \,cm^{2}$, the velocity of water is $1 \,ms^{-1}$ and the pressure is $2000 \,Pa$. The pressure at another point where the cross-sectional area is $5 \,cm^{2}$ is (in $\,Pa$)
