For a casting with a high area to volume (A/V) ratio, one central riser can be enough to feed the entire casting.

For a casting with a high area to volume (A/V) ratio, one central riser can be enough to feed the entire casting. Correct Answer False

Normally, for casting with a high area to volume (A/V) ratio (for example, for a plate and a bar), usually more than one riser is required. And for the low area to volume (A/V) ratio casting like cube and sphere, one central riser can be used to feed the entire casting. In such cases, the proper location of the riser is decided.
