Which one is venturi relation ?
AP1 – P2 = 1/2 ρV22
BV2 = 2g (h1-h2)
CA1 V1 = A2 V2 = constant
DP = 1 /2ρV2 = ρgh = constant
Correct answer
A. P1 – P2 = 1/2 ρV22
Explanation
P1 – P2 = 1/2 ρV22 is the correct answer. Review the question and compare it with the other choices to remember this fact for future exams.
