The dimensions of a cylindrical side riser (height = diameter) for a 25 cm × 15 cm × 5 cm steel casting are to be determined. For the tabulated shape factor values given below, diameter of the riser (in cm) is_______.
Shape Factor 2 4 6 8 10 12
Riser volume/ 1.0 0.70 0.55 0.50 0.40 0.35
Casting volume
-
- 11.60 cm
- 10.66cm
- 10.60cm
- None of the above
Correct Option: C
| Z = | |
| Thickness |
| = | = 8 | |
| 5 |
| = 0.5 | |
| Casting volume |
| = | = 0.5 | |
| 25 × 15 × 15 |
but d = h
| = 0.5 × 25 × 15 × 15 | |
| 4 |
d = 10.60cm
