Smallest in-gate area in the pressurized gating system causes_____(a)

1.	Smallest in-gate area in the pressurized gating system causes_____(a) turbulency(b) low velocity(c) low viscosity(d) smooth running of molten metalThis question was addressed to me in my homework.I want to ask this question from Gating Design topic in division Pattern and Mould, Principles of Gating & Risering of Casting-Forming-Welding I
Answer» Correct option is (a) turbulency Best explanation: In the case of a PRESSURIZED gating system, DUE to the smallest in-gate AREA it maintains a back PRESSURE throughout the gating system. Because of this back pressure in the gating system, the metal is more turbulent and generally flows full.
