Two horizontal cylindrical pipelines A and B contain mineral oil with a density of 900 kg/m3 and water with a density of 1000 kg/m3, respectively. The heights of liquids shown in Fig. , have the following values: hm = 0.2 m; hrt = 0.4 m; hв = 0.9 m. Knowing that the hydrostatic pressure on the axis in pipeline A is equal to 0.6•105 Pa, determine the pressure on the axis of pipeline B.
