In order to measure the air speed in a pipe of radius R, you construct a device which tapers the pipe radius from R to R/2 so that the airflow then passes over R R/2 one end of a U-tube filled with water (not moving) as shown. (Problems 6-8) 6. If the air speed on the right side of the device (where the pipe radius is R) is equal to vo, find an expression for the airspeed on the left side (radius R/2) in terms of vo.
