498 mmHg is 0.6553 atm or 6.638*10^4 N/m^2
You should use N/m^2 units for pressure when you use the equation
delta P = ñ g H = 6.638*10^4 N/m^2
Divide by ñ*g to get the additional height H of the brain above the heart. The density ñ must be in kg/m^3
I get 6.4 meters.
Sounds like a dinosaur.
Calculate the height of the brain above the heart for an animal with an additional blood pressure of 498 mmHg in the heart. Use ρ = 1.057 g/cm3 for the density of blood.
