Water at 65 oF and 20 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. If both streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream.

Explanation:

Equation for mass balance is as follows.

    .......... (1)

Equation for energy balance is as follows.

Hence,       ......... (2)

When we combine both equations (1) an d(2) will be as follows.

or,      

Hence, putting the given values into the above equation as follows.

                            = 594.6 Btu/lbm

Therefore,      

And,      

                           =

                           = 0.415

explanation: look here

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
