Liquid drains from a small hole in a tank, as shown inFig. P4.60, such that the velocity fi eld set up is given byυ r ≈ 0, υ z ≈ 0, υ θ ≈ KR 2 / r , where z = H is the depth of thewater far from the hole. Is this fl ow pattern rotational orirrotational? Find the depth z C of the water at the radiusr = R . Patmz= Hzc?z = 0r= R
