(C) Given: Gauge pressure in the vein,$P = 2000 \; Pa$. Density of blood,$ho = 1.06 	imes 10^{3} \; kg \; m^{-3}$. Acceleration due to gravity,$g = 9.8 \; m \; s^{-2}$.For the blood to enter the vein,the hydrostatic pressure exerted by the blood column in the container must be at least equal to the gauge pressure in the vein.The pressure exerted by the blood column is given by $P = h ho g$,where $h$ is the height of the container.Rearranging for $h$,we get $h = \frac{P}{ho g}$.Substituting the values: $h = \frac{2000}{1.06 	imes 10^{3} 	imes 9.8}$.$h = \frac{2000}{10388} \approx 0.1925 \; m$.Rounding to the nearest significant value,the height must be approximately $0.2 \; m$.

During blood transfusion,the needle is inserted into a vein where the gauge pressure is $2000 \; Pa$. At what height (in $m$) must the blood container be placed so that blood may just enter the vein? (Density of whole blood,$\rho = 1.06 \times 10^{3} \; kg \; m^{-3}$,$g = 9.8 \; m \; s^{-2}$)
