Problem $07\mathrm{.}047-$Entropy change in a rigid tank.

Skip to question

A $1\mathrm{.}200-$ m$3$m$3$ rigid tank contains refrigerant$-134$a initially at $200$ kPa and $40$ percent quality. Heat is transferred now to the refrigerant from a source at $35$C until the pressure rises to $400$ kPa.

Problem $07\mathrm{.}047.$a $-$ Entropy change of R$134$a heated in a rigid tank

Determine the entropy change of the refrigerant. Use the tables for R$-134$a$.$

The entropy change of the refrigerant is kJ$/$K$.$ Determine the entropy change of the heat source.

The entropy change of the heat source is kJ$/$K$.$ Determine total entropy change for this process. $($Round the final answer to four decimal places.$)$

The total entropy change for this process is kJ$/$K$.$
