Blood of density 1010kg/m^3 that is to be administered to a patient is raised about 1.51 m higher than the level of the patient's arm. How much greater is the pressure of the blood than it would be if the container were at the same level of the arm? The acceleration of gravity is 9.8m/s^2. Answer in units of Pa.

In reality, the pressure loss due to the tubing is significant, but well ignore this.

weight of a column blood h height, and area A

weight=density*Volume*g=density*A*h*g
pressure=weight/area=density*g*h

Much easier than I thought: Pressure = (1010 kg/m^3) x (1.51 m) x (9.8 m/s^2) = 14,945.98 Pa

Thanks!

14945.98Pa
