Which of the following statements about a Venturimeter is accurate?

Explanation

Option A is correct because the discharge through a Venturimeter depends only on the pressure difference (Δp) across it and does not vary with the meter’s orientation. Option B is incorrect as flow rate is not significantly influenced by vertical direction under the same pressure difference. Option C is false since considering compressibility typically reduces discharge compared to ignoring it. Option D is wrong because the pressure loss differs between a Venturimeter and a nozzle, even if their throat diameters are equal.
