Explanation By using Bernoulli’s equation, the change in pressure can be determined by the below expression: Δ P = − ρ g h …… (1) Here, ρ is the density of blood, g is acceleration due to gravity and h is distance between the brain and the heart. Given: Blood pressure in your brain while lying down P = 118 mm of Hg Distance between the brain and the heart h = 40 cm Density of the blood ρ = 1060 kg/m 3 Formula used: Δ P = − ρ g h Calculation: Substitute, ρ = 1060 kg/m 3 , 9.8 m/s 2 for g and h = 40 cm in equation (1) so, the change in pressure from the lying position to the stand up position is given as follows: Δ P = − ρ g h = − ( 1060 kg/m 3 ) ( 9
