Why does squeezing a hose make the water go futher?
According to the continuity equation, A1v1 = A2v2, reducing the area of the opening will cause the velocity to increase.
However, according to Bernoulli's eqn, increase in velocity will cause a decrease in pressure, so that will mean that the water will be released at lower velocity. In effect, it should cancel out the increase in velocity due to continuity eqn.
Please help me solve this problem. Thank you!
