m

_{m}= 20 kg

m

_{w}= 1000 kg

T

_{1m}= 800 C

T

_{1w}= 30 C

C

_{pm}= .4 kJ/kg K

C

_{pw}= 4.18 kJ/kg K

With this information, I found T

_{2}to be 304.6 K.

How can I obtain the entropy change with this information? I have no pressure values, and all my entropy equations involve pressure, or specific volume which depends on pressure. Thanks for any help.
