Homework Statement


The container shown in the figure is filled with oil. It is open to the atmosphere on the left.
What is the gauge pressure at point A? Point A is 50cm high from the ground and 50 cm from the top.

Homework Equations


po+(density)gd



The Attempt at a Solution


I took 1 atompshere in Pa of 1.013*105+900*G which is 9.8*.5m and I came up with an answer of 1.057 then I subtracted the gauge pressure of 101.3 kPa and solved for the final answer to be 4,400Pa.

Does anyone come up with the same answer?

What's the density of the oil? Gauge pressure is just (density)gh, so you don't have to calculate total pressure and then subtract atmospheric pressure.
 
The denisty of oil is 900kg/m3
