The liquid in the open-tube manometer in Fig. 12.8a is Mercury , and Atmospheric pressure is 980 millibars. (a) What is the absolute pressure at the bottom of the U-shaped tube? (b) What is the absolute pressure in the open tube at a depth of 4.00 cm below the free surface? (c) What is the absolute pressure of the gas in the container? (d) What is the gauge pressure of the gas in pascals?

Solution 16E Step 1: Introduction : In this question, we have open tube manometer we need to find the absolute pressure at the bottom of the U tube In the second part we need to find the absolute pressure at the 4.00 cm depth below the free surface In the third part we need to find the absolute pressure of the gas in the container In the final part, we need to find the gauge pressure of the gas in pascals Data given Height of Mercury in tube 1 y = 3.00 cm 1 Height of Mercury in tube 2 y =27.00 cm Atmospheric pressure = 980 millibars = 98000 Pa Considering the figure given
