Conservation of Energy, Steady State
A well-insulated water mixer has two inlet pipes, 1 and 2, through
which liquid water
at two different temperatures enters at constant mass flow rates.
A stirring unit mixes the two incoming water streams perfectly with
negligible energy requirements. At exit 3 the mixed water is leaving the
For steady state operation determine the mass flow rate and temperature
of the water at exit 3 using the data provided for inlet 1 and 2.
Assume that the enthalpy of water can be calculated according to :
h = c T
