Problem #$6(25$ points$)$

A well$-$insulated $1\mathrm{.}8$ m$^3$ rigid tank contains steam at $220$C$.$ One third of the

volume $($not the mass$)$ is in the liquid phase and the rest is in the vapor phase.

Determine: a$)$ the pressure of the steam; b$)$ the quality of the saturated mixture

$($note: $0$ x $1)$; and c$)$ the density of the mixture.

Use the property tables included in the textbook appendices

to solve this problem.

a$)$ Pressure $($kPa$)=$

b$)$ Mixture Quality:

b$1)$ Saturated Liquid Volume $($m$^3)=$

b$2)$ Saturated Vapor Volume $($m$^3)=$

b$3)$ Saturated Liquid Specific Volume $($m$^3/$kg$)=$

b$4)$ Saturated Vapor Specific Volume $($m$^3/$kg$)=$

b$5)$ Mixture Quality, x $=$

c$)$ Mixture Density, $($kg$/$m$^3)=$
