The Total solution for NCERT class 6-12
Gauge pressure, P = 2000 Pa
Density of whole blood, ρ = 1.06 × 103 kgm–3
Acceleration due to gravity, g = 9.8 m/s2
Height of the blood container = h
Pressure of the blood container, P = hρg
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.
