Select the correct statement.
A. The discharge through a venturimeter depends upon Δp only and is independent of orientation of the meter
B. 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
C. 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
D. 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
