can you please suggest what kind of methods available to calculate discharge stream properties of the pump

Why do you claim that a positive displacement pump will discharge its liquid at a temperature different than its suction temperature?
Pumps pump liquids; compressors compress gas. Positive displacement compressors adiabatically compress the gas handled and raise its temperature according to the adiabatic process involved. Discharge temperature due to pumping liquids in a pump is something strange to me. Are you confusing liquid pumping with gas compression? And even if there is a temperature increase, it is so slight that it never has come into question in my experience.
I am assuming we are dealing with a steady state pumping operation. If the pump's discharge is closed, or excessively throttled, that is another question - and you haven't defined it.
