The pressure difference measured by a mercury oil differential manometer on the two sides of the orifice meter gives a reading of 50 cm of mercury. Determine the differential pressure head in orifice. Take the specific gravity of oil as 0.9.
- A. 7.05m of oil
- B. 5.05m of oil
- C. 4.75m of oil
- D. 3.35m of oil
Answer: A. 7.05m of oil
Explanation: h = x * ((S_m / S_oil) - 1) = 50 * ((13.6 / 0.9) - 1) cm. h = 50 * (15.11 - 1) = 705 cm = 7.05 m of oil.
