Acylindrical riser is to be designed for a sand casting mold. the length of the cylinder is to be 1.5 times its diameter. the casting is a square plate, each side = 12 in and thickness = 1.1 in. if the metal is cast iron, and the mold constant = 13.0 min/in2 in chvorinov's rule, determine the length of the riser in inches so that it will take 35% longer for the riser to solidify.

d = 2.711

H = 4.06 inch

Explanation:

Given Data:

length = 1.5 times of diameter of cylinder

square plate side = 12 inch, thickness = 1.1 inch

mold constant = 13.0 min/in^2

Casting volume

t is thickness and L is length

substitute t = 1.1 inch, L =12 inch

casting area

A = 340.8 in^2

Ratio between casting volume and area

Total solidification time TST using chvorinov rule

Cm is mold constant

TST = 2.798 min
