A 150 mm long cylinderical rod having a diameter of 100 mm contains six microvoids which are situated at radial distances of 5 mm, 8 mm, 12 mm. 20 mm, 30 mm, 36 mm respectively, on a given r-z plane. Along the length (z-direction) of the rod, the voids are spaced uniformly. The specimen is to be tested by an ultrasonic cylinderical probe, 7.5 mm in diameter: The maximum number of flows, that can be detected in a single measurement by placing the probe at one end of the rod (flat surface) is
