The continuity equation (Av = constant) is derived from the conservation of mass for an incompressible fluid in steady flow. Gravity affects the speed of the fluid, which in turn affects the cross-sectional area to maintain constant volume flow rate.
Consider the following statements : Statement-I: Assertion (A) : The stream of water flowing at high speed from a garden hose pipe tends to spread like a fountain when held vertically up, but tends to narrow down when held vertically down. Statement-II: Reason (R) : In any steady flow of an incompressible fluid, the volume flow rate of the fluid remains constant. Choose the correct answer from the options given below :
