Question 3
XE-EMCQ1 markNeeds review
Two air streams of mass flow rates
and
enter a mixing chamber and exit after perfect mixing. The corresponding temperatures of the inlet streams are
and
, respectively. Heat loss rate from the mixing chamber to the surrounding is
. Assume that the process is steady, specific heat capacity is constant, and air behaves as an ideal gas. Identify the correct expression for the final exit temperature
after mixing. The mass specific heat capacities of the gas at constant volume and constant pressure are
and
, respectively. Neglect the bulk kinetic and potential energies of the streams.Your answerChoose one option.
