## Homework Statement

A 0.3 m long tube is filled with sterile solution of density 1037 kg m-3 and closed at the top. The tube is tilted at 40°. to the horizontal. The gauge pressure at the base of the tube is 3000 Pa. What is the gauge pressure at the top of the tube (in Pa)?

## Homework Equations

## The Attempt at a Solution

So I assumed that the tilting would have no effect so I just used pgh to find the weight of the fluid up until the bottom but that didnt even give me 3000 ... i got 3111

im really confused as how to how to respond to the change in angle.

cheers
