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? [use the density of whole blood from table].

Text Solution

Verified by Experts

The correct Answer is:
A
Pressure `P=hrhogimpliesh=(2000)/(1.06xx10^(3)xx9.8)=0.192m`
