Write and simplify the general energy balance for these open systems. Clearly state/draw where inlet point and outlet point are in your system (this will affect your answer). State if heat and shaft work are positive or negative (if non-zero).

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

On a average work day more than work place firs are reorted

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false
