When measuring small pressure differences with a manometer, often one arm of the manometer is inclined to improve the accurac reading. (The pressure difference is still proportional to the vertical distance and not the actual length of the fluid along the tube) air pressure in a circular duct is to be measured using a manometer whose open arm is inclined 45 from the horizontal, as shown the figure The density of the liquid in the manometer is 0.79 kg/L and the vertical distance between the fluid levels in the two arms of the manometer is 12 cm. Determine the gage pressure of air in the duct and the length of the fluid column in the inclined arm ab the fluid level in the vertical arm Air Duct 12 cm 45 The gage pressure of air in the duct is The length of the fiuid column is cm
