Problem $2$: Propane flows through the condenser of an air

conditioner, which cools hot, high$-$pressure refrigerant vapor,

causing it to decrease in temperature and partially $($or fully$)$

condense. Condensers do not produce shaft work. The propane

flowrate is $0\mathrm{.}034k\frac{g}{s}.$ You measure the specific volume of the

vapor as it enters and exits the condenser. The specific volume at

the inlet is $0\mathrm{.}05505\frac{m^3}{k}g($state $1),$ while the specific volume at

the outlet is ${2\mathrm{.}04310}^{-3}\frac{m^3}{k}g($state $2).$ You also measure the

pressure in the condenser, which is constant throughout the

condenser with a value of $10$ bar. Assume that the ideal gas law

is not applicable for the inlet vapor. Assume that the system is at

steady state. Find:

$($i$)$ The temperature of the inlet vapor $($state $1),$ in $C,$ to the

nearest whole number

$($ii$)$ The enthalpy of the inlet vapor $($state $1),$ in $k\frac{J}{k}g,$ to the

nearest two decimal places

$($iii$)$ The temperature of the propane as it leaves the condenser

$($state $2),$ in $C,$ to the nearest two decimal places

$($iv$)$ The quality of the propane as it leaves the condenser

$($state $2),$ to the nearest two decimal places

$($v$)$ The enthalpy of the propane as it leaves the condenser

$($state $2),$ in $k\frac{J}{k}g,$ to the nearest two decimal places

$($vi$)$ The rate of heat transfer for the condenser control

volume, in W $,$ to the nearest whole number

$($vii$)$ Draw the condenser control volume for your schematic,

and label both states

For Problems $2$ and $3,$ I have given you all the different tables

for propane $($see the final pages of the homework document$)$; it

is up to you to figure out which tables you actually need to solve

the problems.
