The speed of blood through the aorta is 0.265 m/s.
The speed of blood flow through aorta is termed as volumetric flow rate. The formula is -
Q = Av, where Q is volumetric flow rate, A is area and v represents speed.
Area = πr²
As we know, 1 m = 100 cm
So, 1 cm = 0.01 m
Area = π(0.01)²
Area = 3.1× [tex] {10}^{ - 4} [/tex] m²
Q = 5 l/min
Converting to m³/sec
Q = 5/1000×1/60
Q = 8.3 × [tex] {10}^{ - 3} [/tex] m³/s
Now calculating v or speed of blood
v = Q/A
v = 8.3 × [tex] {10}^{ - 3} [/tex] ÷ 3.1× [tex] {10}^{ - 4} [/tex]
v = 0.265 m/s
Thus, the blood flows at 0.265 m/s through aorta.
