Required information

Problem $04\mathrm{.}031$E $-$ Energy balance for R$134$a in a rigid

tank

A $17\mathrm{.}00-f{t}^3$ rigid tank initially contains saturated refrigerant$-$

$134$a vapor at $160$ psia. As a result of heat transfer from the

refrigerant, the pressure drops to $50$ psia.

Problem $04\mathrm{.}031$E$.$c $-$ Find condensing mass

Determine the amount of refrigerant that has condensed. $($Round the final

answer to three decimal places.$)$

The amount of refrigerant that has condensed is

Ibm $.$
