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.

Respuesta :

Answer:

it will take for the casting to solidify 2.55 min

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 × [tex](\frac{V}{A})^{1.9}[/tex]   ..............1

put here value

Chvorinov's Rule = 4 × [tex](\frac{600}{760})^{1.9}[/tex]  

Chvorinov's Rule = 2.55 min/in

so heer unit flow become [tex]min/in^{1.9}[/tex]
