20.An engine pump is used to pump a liquid ofdensity ρcontinuously through a pipe ofcrossectional area A. If the speed of flow ofthe liquid in the pipe is v, then the rate atwhich kinetic energy is being imparted to theliquid is(A)-Apv3(B) Apv222(C) Apv(D) Apv |

Answer» Rate of liquid flow =(1/2*m*v^2)/tRate of flow =m/tRate of flow=dV/tRate of flow=dAL/t1/2* d*A*v *v^21/2 *dAv^3 |
