Problem $1.$

a$.$ Water at $220C$ and has internal energy of $2000K\frac{J}{k}g.$ Determine quality $x,$ specific volume, specific entropy, and specific enthalpy

b$.$ If the total volume of the container is $5m^3,$ how much vapor mass we have, also how much liquid water we have.

c$.$ Find u$,$ h$,$ and s for water @ $800$ kPa and $1000C?$

d$.$ Find $u,h,$ and s for water @ $20C$ and $2000$ kPa $?$
