Question

In the casting of steel under certain mold conditions, the mold constant in Chvorinov's Rule is known to be 4.0 min/cm2, based on previous experience. The casting is a flat plate whose length = 35 cm, width = 10 cm, and thickness = 15 mm. Determine how long it will take for the casting to solidify.

Answer 1

it will take for the casting to solidify 2.55 min

Step-by-step explanation:

given data

mold constant = 4 min/cm²

length = 35 cm

width = 10 cm

thickness = 15 mm

solution

we use here Chvorinov's Rule that is

Chvorinov's Rule = mold constant ×
`((V)/(A))^(1.9)` ..............1

put here value

Chvorinov's Rule = 4 ×
`((600)/(760))^(1.9)`

Chvorinov's Rule = 2.55 min/in

so heer unit flow become
`min/in^(1.9)`
