1.	Which of the following is a key parameter when we design a riser using Novel research method?(a) Modulus(b) Freezing ratio(c) Shape factor(d) Shrinkage volumeI had been asked this question in an interview.I want to ask this question from Riser Design topic in portion Pattern and Mould, Principles of Gating & Risering of Casting-Forming-Welding I
Answer» Right answer is (c) SHAPE factor To EXPLAIN: Modulus is used for designing of riser using modulus method. The FREEZING ratio is a key parameter when we design riser using Caine’s method. SHRINKAGE volume is used when we use the shrinkage volume method. For Novel research method, we use shape factor and CORRESPONDING to this we find Y from casting databook which is the ratio of the volume of casting to the volume of the riser.
