Determine the difference in the blood pressure from feet to top
This is calculated using Pascal's second law.
The second law is represented as:

Subtract P1 from both sides

Where



P2 - P1 = Blood Pressure Difference
So, the expression becomes:



Hence, the difference in blood pressure is approximately
