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

The tilting would change the vertical height. It would be like a right angled triangle. I also think Bernoulli's equation would work here.
