- Explain important rules that must be kept in mind while designing casting?arrow_forwardA riser in the shape of a sphere is to be designed for a sand casting mould at Simon Castings. The casting is a rectangular plate, with length = 400 mm, width = 250 mm, and thickness = 15 mm. If the total solidification time of the casting itself is known to be 7 min, determine the diameter of the riser so that it will take 30% longer for the riser to solidify.arrow_forwardFor sand-casting a steel rectangular plate with dimensions 80mm×120mm×20mm, a cylindrical riser has to be designed. The height of the riser is equal to its diameter. The total solidification time for the casting is 2 minutes. In Chvorinov‟s law for the estimation of the total solidification time, exponent is to be taken as 2. For a solidification time of 3 minutes in the riser, the diameter (in mm) of the riser is ____arrow_forward
