Explanation of Bernoulli’s equation
Thread Content
In Bernoulli’s equation, P1 + (ρ×V1×V1)/2 + ρ×g×h1 = P2 + (ρ×V2×V2)/2 + ρ×g×h2. As shown in the diagram, the liquid flows from the small tube into the larger tube. Assuming that both tubes are filled with liquid, an increase in the area of the larger tube leads to a decrease in V2 (since V = Q/S), and an increase in area also results in a decrease in P2 (since P = F/S). Then, does this equation no longer hold true? I beg the experts to help me!
The statement that the area increase leads to a decrease in P2 (P=F/S) is incorrect.
P2 should be increased; P2 > P1
