The inclined differential manometer of the figure below contains carbon tetrachloride. Initially the pressure differential between pipes A and B, which contain a brine (SG = 1.1), is zero as illustrated in the figure. It is desired that the manometer give a differential reading of 0.3 m (measured along the inclined tube) for a pressure differential of 0.7 kPa. Determine the required angle of inclination, θ. 4.
