Physics Pressure Problem (Systolic blood pressure of a giraffe)

[aryan15]

Homework Statement:

The systolic blood pressure of a giraffe is 288.0 mmHg. This is the blood pressure inside the giraffe's body at the height of the heart when the heart contracts. However giraffes have very long necks. If the head of a giraffe is 1.70 m above its heart, then what is the blood pressure in the giraffe's brain?

Relevant Equations:

The density of Mercury is 13534 kg/m^3, and the average density of giraffe blood is 1050 kg/m^3.

Absolutely no idea how to go about this question. An answer with an explanation would be highly appreciated. Thanks!

Well I don't have any idea either, but in order for anyone to help you need to show your best effort to solve the problem. See:

What is the relationship between pressure, density, and depth or elevation?
