STEAM EXERCISE #$1$

State $1$: Steam at $600$ psia saturated vapor

State $2$: Expanded to $14\mathrm{.}7$ psia. The specific volume of the steam at $14\mathrm{.}7$ psia is $10$ times that of

State $1.$

Assume that changes in kinetic and potential energy are negligible and there is no heat transfer.

Find:

a$.$ The quality at State $2$

b$.$ The change in enthalpy from State $1$ to State $2$

c$.$ How do you account for $($explain$)$ the change in enthalpy from State $1$ to State $2?$

STEAM EXERCISE #$2$

State $1$: $600$ psia saturated liquid $($water$)$

State $2$: Heated in constant pressure process to a quality of $x=\mathrm{.}5$

Assume that changes in kinetic and potential energy are negligible and there is no work.

Find:

a$.$ How much heat was added on a BTU$/$Ibm basis?

b$.$ The enthalpy and specific volume at State $2$

STEAM EXERCISE #$3$

State $1$:$600$ psia saturated liquid $($water$)$

State $2$ : Expanded to $10$ psia in a constant enthalpy process.

Find:

a$.$ The quality at State $2$
