Answer:
P₂ = 1.99 x 10⁴ Pa
Explanation:
given,
blood pressure at an instant = 1.5 x 10⁴ Pa
density of blood is equal density of water = 1000 kg/m³
depth = 0.5 m
Pressure below the heart = ?
[tex]P_2 = P_1 + \rho g h[/tex]
P₂ is the required pressure at 0.5 m depth
P₁ is the blood pressure in heart
g is the acceleration due to gravity
now,
[tex]P_2 = 1.5\times 10^4 + 1000\times 9.8 \times 0.5[/tex]
P₂ = 19900 Pa
P₂ = 1.99 x 10⁴ Pa
Hence, the pressure below 0.5 m is equal to P₂ = 1.99 x 10⁴ Pa
