Moment of a force is not a free vector. There are certain quantities along the line with which force is applied.
Force can be moved in any direction along the line of the action without changing the external reaction.
The magnitude of equivalent resultant force is distributed along the centroid point.
The resultant force of a couple force system is zero as it form opposite forces which balances off each other.

Explanation:
For this problem you must use 2 equations, the first is the continuity equation that indicates that all the mass flows that enter is equal to those that leave the system, there you have the first equation.
The second equation is obtained using the first law of thermodynamics that indicates that all the energies that enter a system are the same that come out, you must take into account the heat flows, work and mass flows of each state, as well as their enthalpies found with the temperature.
finally you use the two previous equations to make a system and find the mass flows
