A differential mercury manometer connected between two points in a water pipe shows a deflection of 200 mm. What is the pressure difference between the two points? (same elevation, SG Hg = 13.6)
- 26.68 kPa
- 1.96 kPa
- 24.72 kPa
- 28.65 kPa
Answer
C. 24.72 kPa
Solution
P = (SG Hg - SGw) w h = (13.6 - 1)(9.81)(0.2) = 24.72 kPa.
