Steady-state flow exists in a pipe that undergoes a gradual expansion from a diameter of 16 in. to a diameter of 4 in. The density of the fluid in the pipe is constant at 60.8 lbm/ft. Given: pA1V1 PA2V2 If the flow velocity is 22.6 ft/sec in the 16 in. section, the flow velocity in the 4 in. section is ft/sec. O 83.3 O 97.6 72.2 O90.4
