Problem 2 (a): A mold has a downsprue of length = 6.0 in. The cross-sectional area at the bottom of the sprue is 0.5 in? The sprue leads into a horizontal runner that feeds the mold cavity, whose volume = 75 in'. Determine (a) the velocity of the molten metal flowing through the base of the downsprue, (b) the volume rate of flow and (c) the time required to fill the mold cavity.

Provide the formula please for each part solved
A solid hexagonal shaped casting of thickness 3 cm and each side as 8 cm is being casted in a sand mold. The distance from top of the pouring cup to the sprue bottom is 20 cm, which is along the parting line. The diameter of the circular cross section at the base of sprue is 1.5 cm. The part is fully buried in drag side of the mold and top surface...

Question: During a sand casting process, the constant C in Chvorinov’s rule is 3 s/mm2. The process is used to produce a hollow cylindrical casting with an OD (outside diameter) of 75 mm, ID (inside diameter) of 50 mm, and a height of 125 mm. The mold contacts the cylinder on both the OD and the ID surfaces. a) Estimate the time for the casting to fully solidify. b) Write the equation used to calculate Chvorinov’s constant C. Based on...

(Metal-Casting Processes) (Groups) 10.47 A round casting is 0.2 m in diameter and 0.75 m in length. Another casting of the same metal is elliptical in cross-section, with a major-to-minor axis ratio of 2, and has the same length and cross-sectional area as the round casting. Both pieces are cast under the same conditions. What is the difference in the solidification times of the two castings? 10.48 A cylinder with a diameter of 50 mm and a height of 75...

3. Application to manufacturing/Sprue design: Assume that the top of a round sprue has a diameter (d) of 4 in. and is at a height of 12 in. from the runner. Plot the profile of the sprue diameter as a function of its height, to avoid voids between the stream of molten metal flowing through the sprue and the sprue walls. Assume that the sprue has a diameter (d) of 1 in at its bottom. Hint: Make the reference height...
