(b) In casting experiments performed using a certain alloy and type of sand mould, for which n can be approximately taken as 2, it took 155 sec for a cube-shaped casting to solidify. The cube was 50 mm per side. (i) Determine the value of the mould constant in Chvorinov's rule. (ii) When the same alloy and mould type are used to make a cylindrical casting of diameter 30 mm, what is the maximum length of the cylinder if the maximum solidification time is limited to 1 minute?

2. In the casting of steel under certain mould conditions, the mould constant in Chvorinov's rule is known to be 4.0 min/cm?, based on previous experience. The casting is a flat plate whose length is 25 cm, width is 8 cm, and thickness is 2.5 cm. Exponent n is taken to have a value of 2. Determine how long it will take for the casting to solidify.
h, is placed on the top of the mold cavity of a closed type sand mould as shown in the figure. If the riser is of constant volume, then the rate of solidification in the riser is the least when the lindrical blind riser with diameter dand height is ratio h: d is Sprue basin Riser Mould cavity
A flat plate is to be cast in an open mold whose bottom has a square shape that is 200 mm by 200 mm. The mold is 40 mm deep. A total of 106 mm3 of molten aluminum is poured into the mold. Solidification shrinkage is known to be 6.0%. The linear shrinkage due to thermal contraction after solidification is 1.3%. If the availability of molten metal in the mold allows the square shape of the cast plate to maintain its 200 mm by 200 mm dimensions until solidification is completed, determine the final dimensions of the plate.
A flat plate is to be cast in an open mold whose bottom has a square shape of 12.5 cm by 12.5 cm. The mold is 7.0 cm deep. A total of 350 cm³ of molten aluminum is poured into the mold. Solidification shrinkage is known to be 6.25%, which is a volumetric contraction, not a linear contraction. Table 7.1 lists the linear shrinkage due to thermal contraction after solidification. If the availability of molten metal in the mold allows the square shape of the cast plate to maintain its square dimension until solidification is completed, determine the final dimensions (width and height) of the plate.
