Here is the solution to the question. 10. The figure below shows a water U-tube manometer used to measure the gas pressure of a gas supply. Step 1: Identify the height difference in the manometer. From the figure, the difference in the water levels between the two arms is 9 cm. h = 9 cm Step 2: Convert the height difference to meters. h = 9 cm = 0.09 m Step 3: State the known values for water and gravitational field strength. Density of water = 1000 kg/m^3 Gravitational field strength g = 9.8 N/kg Step 4: Calculate the gauge pressure of the gas. The gauge pressure of the gas is equal to the pressure exerted by the column of water of height h. P = g h P = (1000 kg/m^3) × (9.8 N/kg) × (0.09 m) P = 9800 Pa/m × 0.09 m P = 882 Pa The gauge pressure of the gas is 882 Pa. 4 done, 1 left today. You're making progress.
