During blood transfusion the needle is inserted in a vein where the gauge pressure is `2000Pa` . At what height must the blood container be placed so that blood may just enter the vein? Density of whole blood = `1.06xx10^(3)Kg//m^(3)`.

Text Solution

Verified by Experts

`h=P//rhog=200//(1.06xx10^(3)xx9.8)=0.1925m`
The blood may just enter the vein if the height at which the gblood container be kept must be slightly greater than `0.1925m` i.e., 0.2m.
