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]
