There should be mercury in both sides of the tube, with a higher column height on the side opposite to the side with the gas.
The gas pressure equals
P= (mercury density) g h,
where h is the difference in the mecruty column heights.
You do not have to add 101300 (atmosheric pressure) to get the absolute pressure with a u-tube manometer such as this.
P = 9.81 m/s^2*13600 kg/m^3*(.16-.06) m
i got 13341.6 ...it is incorrect
i figured it out..thanks for helping me
Annie, how can you say that...it is my question i am still working on it
sorry Ana... i missed typed it...again i apologize
