U-tube manometer problems and solutions lecture
8. Find the difference of pressure between the tanks A and B.
9. At position A the gage pressure is -11KPa. Find the specific gravity of liquid B.
10. Pressures in the pipe A and B are 280KPa and 140KPa respectively. Find the deflection of the mercury in the differential manometer.
11. A certain liquid is flowing through a vertical pipe having specific gravity of 1.55. Find the difference of pressure between sections x and y. The specific gravity of manometric fluid is 0.76.
12. A certain oil is flowing through a horizontal pipe. The pressure at point A is 138KPa. If specific gravity of oil is 0.80, find the deflection h of the manometer. The manometric fluid is mercury.

13. In a horizontal pipe a differential manometer is attached to two cross sections in which water is flowing. The deflection in the manometer is equal to 0.60m. Calculate the difference in pressure in KPa between sections A and B.
14. Develop an expression for the pressure difference (∆P=P_A-P_B).
