Question

The pressure at a point in the fluid is 4.9 N/cm2. Find height when the fluid under consideration is in oil of specific gravity of 0.85.

(a) 5.83 m

(b) 11.66 m

(c) 17.49 m

(d) 8.74 m

This question was posed to me during an interview for a job.

This intriguing question comes from Fluid Pressure at a Point and Pascal’s Law in division Pressure and Its Measurement of Fluid Mechanics

Answer 1

Right choice is (a) 5.83 m

To explain: Height=p/ρg

                               =48620/850*9.81

                               =5.83 m.
