Question

According to the empirical relationship, total solidification time is proportional to which one of the following quantities: (a) (A/V)n, (b) Hf, (c) Tm, (d) V, (e) V/A, or (f) (V/A)2; where A = surface area of casting, Hf = heat of fusion, Tm = melting temperature, and V = volume of casting?

Answer 1

(f) (V/A)²

Step-by-step explanation:

The solidification time relationship given as

`t=K\left((V)/(A)\right)^2`

Where

K= Constant

A=Surface area

V=Volume

t=Solidification time

So from above expression we can say that t is directly proportional to the (V/A)².

t ∝ (V/A)²

So the option f is correct.

(f) (V/A)²
