An engine pump is used to pump a liquid of density $\rho$ continuously through a pipe of cross-sectional area $\mathrm{A}$. If the speed of flow of the liquid in the pipe is $\mathrm{v}$, then the rate at which kinetic energy is being imparted to the liquid is (A) $(1 / 2) \mathrm{A} \rho \mathrm{V}^{3}$ (B) $(1 / 2) \mathrm{A} \rho \mathrm{V}^{2}$ (C) $(1 / 2) \mathrm{A} \rho \mathrm{V}$ (B) $\mathrm{ApV}$
A fluid flows steadily through a pipe with a uniform cross-sectional area. The density of the fluid decreases to half its initial value as it flows through the pipe. The correct statement about the average velocity V is: _______ rho1 → rho2 = rho1/2 V1 → V2 = ? a. V2 equals 2V1. b. V2 equals V1/2. c. V2 equals V1. d. V2 equals V1/4. e. V2 equals 4V1.
