Answer
The blood flow in artery of a human being can be easily explained on the basis of Bernoulli's principle. The heart applies a pressure to maintain blood flow through the arteries.
In persons suffering with advanced heart condition, the artery gets constricted due to the accumulation of plaque on its inner walls. In order to drive the blood through this constriction a greater activity of the heart is required. The speed of the flow of the blood in this region is raised which lowers the pressure inside, and the artery may collapse due to this external pressure.
The heart exerts further pressure to open this artery and forces the blood through. As the blood rushes through the opening, the internal pressure once again drops leading to a repeat collapse. This may result in heart attack.

An ice cube of mass 0.1 kg at $0^{\circ} C$ is placed in an isolated container which is at $227^{\circ} C$. The specific heat S of the container varies with temperature T according to the empirical relation $S = A + BT$, where $A =100 cal / kg - K$ and $B=2 \times 10^{-2} cal / kg - K ^2$. If the final temperature of the container is $27^{\circ} C$, determine the mass of the container. (Latent heat of fusion of water $=8 \times 10^4$ call kg. Specific heat of water $=10^3 cal / kg - K$ ).
