Acceleration due to gravity, \(g=9.8 m / s ^{2}\) Height of the blood container \(=h\) Pressure of the blood container, \(P=h \rho g\) \(\therefore h=\frac{P}{\rho g}\)
\(=\frac{2000}{1.06 \times 10^{3} \times 9.8}\)
\(=0.1925 m\)
The blood may enter the vein if the blood container is kept at a height greater than \(0.1925\; m\), i.e., about \(0.2 m\)
