The discharge through a venturimeter depends upon ?p only and is independent of orientation of the meter
A venturimeter with a given gage difference discharges at a greater rate, when the flow is vertically downward through it, than when the flow is vertically upward
For a given pressure difference, the discharge of gas is greater through a venturimeter, when compressibility is taken into account, than when it is neglected
The overall pressure loss is the same in a given pipe line, whether a venturimeter or a nozzle with the same throat dia is used
✅ The correct answer is option A.
