86 N/cm"] 11. A single column vertical manometer (ie., micrometer) is connected to a pipe containing oil of sp. gr. 0.9. The area of the reservoir is 80 times the area of the manometer tube. The reservoir contains mercury of sp. gr. 13.6. The level of mercury in the reservoir is at a height of 30 cm below the centre of the pipe and difference of mercury levels in the reservoir and right linb is 50 cm. Find the pressure in the pipe. (Ans. 6.474 N/em) 12. A pipe contains an oil of sp. gr. 0.8. A differential manometer connected at the two points A and B of the pipe shows a difference in mercury level as 20 cm. Find the difference of pressure at the two paints. [Ans. 25113.6 N/m³) 13. A U-tube differential manometer connects two pressure pipes A and B. Pipe A contains carbon tetrachlo- ride having a specific gravity 1.594 under a pressure of 11.772 N/cm and pipe B contains oil of sp. gr. 0.8 under a pressure of 11.772 N/cm. The pipe A lies 2.5 m above pipe B. Find the difference of pressure measured by mercury as fluid filling U-tube. (A.M.I.E. December, 1974) (Ans. 31.36 cm of mercury] 14. A differential manometer is connected at the two points A and B as shown in Fig. 2.25. At B air pressure is 7.848 N/cm (abs.), find the absolute pressure at A.
