Impellers in a motor in a fluid mechanical system intercept flowing fluid in a pipe and convert the kinetic energy of the fluid to electrical energy. The power that is harvested by the motor is given by: P = - PAev' where P = power harvested (W) density of fluid (kg/m') A cross-sectional area of the impellers (m') efficiency of motor velocity of fluid (m's) This system uses water of known constant density 990 kp/m' with impellers of known cross- sectional area 0.0025 m and a motor of efficiency 58%. If the water velocity is measured to be 2.40+0.05 m/s, determine the power and the uncertainty in the power delivered by the motor,
