Carbon dioxide $(=7\mathrm{.}62{10}^{-3}$ slugs $\{\frac{\text{:}}{f}{t}^3)$ flows through a pipe at a rate of $2f\frac{t^3}{s}$ as shown below. The pressure at section

$(1)$ is $p_1=2000l\frac{b}{f}{t}^2.$

$D_1=4in$

The velocity at section $(1)$ is $V_1=$

$127\mathrm{.}68$

$f\frac{t}{s}.($Ex: $11\mathrm{.}2)$

The velocity at section $(2)$ is $V_2=$

$f\frac{t}{s}.($Ex: $111\mathrm{.}2)$

The pressure at section $(2)$ is $p_2=$

$l\frac{b}{f}{t}^{?}2.($Ex: $1234)$
