- [KVPY 2020]
- A
As the platelets enter a constriction, the platelets get squeesed closer together in the narrow region and hence the fluid pressure must rise there
- B
As the platelets enter a constriction, pressure is lower there
- C
The 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
- D
Pressure is same in all the parts of the artery

A train with cross-sectional area $S _{ t }$ is moving with speed $v_t$ inside a long tunnel of cross-sectional area $S _0\left( S _0=4 S _{ t }\right)$. Assume that almost all the air (density $\rho$ ) in front of the train flows back between its sides and the walls of the tunnel. Also, the air flow with respect to the train is steady and laminar. Take the ambient pressure and that inside the train to be $p _0$. If the pressure in the region between the sides of the train and the tunnel walls is $p$, then $p _0- p =\frac{7}{2 N } \rho v_{ t }^2$. The value of $N$ is. . . . .
