(a)
Interpretation:
Percent shrinkage during solidification of iron casting needs to be determined.
Concept Introduction:
Solidification is the process of forming a crystal structure form the molten metal.
Shrinkage is the defect in cast product occurred during solidification
Change in volume takes place due to Shrinkage
The material shrinks up to 7% during solidification volume of shrinkage material can be calculated as
Where,
r =radius of material
(b)
Interpretation:
Number of shrinkage pores in casting can be calculated as follows:
