Two important relationships that determine the flow of molten metal in casting are which of the following:
(a) Bernoulli’s theorem,
(b) Chvorinov’s rule,
© continuity law,
(d) flow curve,
(e) Hooke’s law,
(f) Ohm’s law?

Bernoulli’s theorem plays a pivotal role in understanding how fluid velocity and pressure interact during the casting process. It helps predict how the molten metal will flow through the gating system, ensuring that it fills the mold efficiently and evenly. Without this principle, we could face issues like incomplete molds or turbulence that can cause defects in the final cast.

Chvorinov’s rule, on the other hand, is essential for determining solidification times in casting. It states that the time required for a casting to solidify is proportional to the square of its volume divided by its surface area. This relationship helps engineers design molds and casting methods that optimize cooling rates, ensuring high-quality final products devoid of defects.
