Answer to Question #37596 in Mechanics | Relativity for Satyam Sharma

Question

Let there be a tube making an angle θ with the earth surface through which water is passing. Let the flow be streamline. Assume two cross sections A1 and A2(A1 ≠ A2) through which water is passing at a velocity of v1 and v2 respectively.
Then by Equation of Continuity A1. v1=A2 . v2
But as the water is going upward why don’t we consider the effect of the acceleration(due to gravity) on velocity i.e. why don’t we substitute v1 and v2 with its value calculated with the help of the 3 eqations of Motion(I AM NOT TALKING ABOUT THE VARIATION OF ‘g’ WITH HEIGHT BUT EFFECT OF ‘g≈9.8 m/s2 on the velocity of water)
Please Help Its urgent
