Answer:
![P_2-P_1=27209h](https://tex.z-dn.net/?f=P_2-P_1%3D27209h)
Explanation:
For pressure gage we can determine this by saying:
The closed tank with oil and air has a pressure of P₁ and the pressure of oil at a certain height in the U-tube on mercury is p₁gh₁. The pressure of mercury on the air in pressure gauge is p₂gh₂. The pressure of the gage is P₂.
![P_1+p_1gh_1=p_2_gh_2+P_2](https://tex.z-dn.net/?f=P_1%2Bp_1gh_1%3Dp_2_gh_2%2BP_2)
We want to work out P₁-P₂: Heights aren't given so we can solve it in terms of height: assuming h₁=h₂=h
