irks = 10 marks) i. A melt is poured in a mould with a velocity 1m/s through bottom of sprue which has a diameter of 5mm. Determine whether the flow in turbulent. Assume the properties of melt as density (p) = 7860 kg/m3 and viscosity at pouring temp (u) = 2.25 x 10-3 Ns/m2. ii. Briefly explain the principles of fluid flow significant in gating design.
