Metal Casting Example Problem | Riser Design Calculation

Riser Design Calculation in metal casting process included in this video. A cylindrical riser must be designed for a sand casting mold. The casting itself is a steel rectangular plate with dimensions 7.5cm x 12.5cm x 2cm. Previous observations have indicated that the total solidification time for this casting is 1.6 minute. The cylinder for the riser will have a diameter to height ration is 1. Determine the dimensions of the riser so that its solidification time is equal to 2 minutes.(take n=2)
