For the shown casting in figures:

Given that: the effective poring height is $200$ mm $,$ casting yield is $0\mathrm{.}65,$ material density $\backslash (7800\backslash$mathrm$\{$Kg$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash ),$ efficiency factor $\backslash (=0\mathrm{.}7\backslash ),$ and the pouring time equation: $\backslash (\backslash$mathrm$\{$t$\}=1\mathrm{.}84\backslash$sqrt$\{$W$\_\{$t$\}\}\backslash )$ sec$.$ Where $\backslash (\backslash$mathrm$\{$W$\}\_\{\backslash$mathrm$\{$t$\}\}\backslash )$ is the total poured weight in Kg $.$

a$-$ Draw a suitable pattern showing the parting line $($or lines$)$ and the core prints $($necessary modification are allowed$).$

b$-$ Calculate the dimensions of the feeder required to feed the casting.

c$-$ Calculate the gating dimensions, Sprue, Runner, and Ingate.

d$-$ Draw a neat sketch of the mold just before pouring showing all detail.
