During blood transfusion the needle is inserted in a vein where the gauge pressure is 2000 pa. At what height must the blood container be placed so that blood may just enter the vein? Density of whole blood =\[p=80\cdot 0\times 1\cdot 013\times {{10}^{5}}pa;\]

Answer:

\[\frac{1}{B}=45\cdot 8\times {{10}^{-11}}P{{a}^{-1}}\] The blood may just enter the vein if the height at which the blood container be kept must be slightly greater than \[p=1\cdot 03\times {{10}^{3}}kg{{m}^{-3}}\]
