A cylindrical riser with a diameter-to-length ratio = 1.0 is to be designed for a sand-casting mold. As shown in Figure P10.20; the units are inches. If the mold constant in Chvorinov’s rule = 25.3 min/in2, calculate the dimensions of the riser so that the riser will take 1.0 min longer to freeze than the casting itself.
