In the inverted U-tube Differential manometer, how is the specific gravity of manometric fluid used relative to the fluid flowing in the pipes
(a) Specific gravity is more than that of fluid flowing in pipes
(b) Specific gravity is less than that of fluid flowing in pipes
(c) Specific gravity is equal to that of fluid flowing in pipes
(d) None of the mentioned
The question was asked by my school teacher while I was bunking the class.
This intriguing question comes from Measurement of Pressure, Simple and Differential Manometers topic in division Pressure and Its Measurement of Fluid Mechanics
