a person is 1.8 m tall, standing upright. His heart is 1.4m above his feet. He is doing a head stand. Calculate the hydrostatic blood pressure in (a) his feet and (b) his head.
P-Po= density x g x d
The Attempt at a Solution
When standing upright:
Pheart-Pbraind=1059.5 x 9.81 x 0.4
13500-Gauge P in brain= 9.3 KPa
Pfeet-Pheart=1059.5 x 9.81 x 1.4
feet-13500=1059.5 x 9.81 x1.4
P feet= 28 KPa
How do I know what distance to use when he is upside down? You would think these numbers would just be opposite?
