To determine Determine the thickness of the water stream at the base of the cone. Explanation Consider a control volume attached to the cone and write the continuity equation. V 1 A 1 = V 2 n A 2 V 1 π r 1 2 = V 1 cos θ π [ ( r 2 + δ ) 2 − r 2 ] δ 2 + 2 r 2 δ − r 1 2 cos θ = 0 (I) Here, velocity of the incoming jet and flow leaving at the base of the cone is V 1 and V 2 n respectively, cross-sectional area of base of jet and flow area in the plane of the cone base is A 1 and A 2 respectively, the thickness of the water stream in the radial direction is δ , initial and final radius is r 1 and r 2 respectively and angle of the jet is θ . Express the thickness of the water stream at the base of the cone. t = δ cos θ (II) Conclusion: Substitute 0 .05 m for r 1 , 0
