The density of Class $"G")=(3\mathrm{.}14$ cement is needed to increase to $18\mathrm{.}2lb\frac{m}{g}al$ by adding Barite $=4\mathrm{.}23).$ The water volume requirements are

Class $"$G$"$ cement : $5$ gal$/94-$lbm sack

Barite: $2\mathrm{.}4ga\frac{l}{100}-1bm$ sack

a$)$ What is the amount of Barite needed to be mixed with each sack of cement? $(4$ points$)$

b$)$ What is the slurry yield? $(2$ points$)$

c$)$ What is the "percent mix" of the slurry? $(2$ points$)$

d$)$ How many sacks of cement are needed to seal an open hole interval having a volume of $70$ bbl$?(2$ points$)$
