(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
