Answer:
h = 1.22 m
Explanation:
Given:
Pressure in the vein = 12200 Pa
Specific gravity of the liquid = 1.02
now,
the pressure due to a fluid is given as:
P = pgh
where,
P is the pressure,
ρ is the density of fluid = specific gravity x density of water = 1.02 x 1000 kg/m³
ρ = 1020 kg/m³
g is the acceleration due to the gravity = 9.81m/s²
h is the height
thus,
h = P/pg =
