A mold is being designed to cast a tube of a pure metal, 1 m long with an outer diameter of 20 cm and an
inner diameter of 16 cm. The proposed riser is a spherical cavity. If the mold constant is 3 min/cm2 and the mold exponent is 2, determine the minimum diameter of the riser that will prevent a defect in the casting. 1b)
Draw and label the microstructure of a section through the casting perpendicular to its axis well away from the downspout or the riser.
please show all work and steps clearly so I can follow your logic and learn to solve similar ones myself. Will rate your answers. Thank you kindly!
