I have a refrigeration system with a hot gas bypass line installed, which connects the discharge of the compressor to the suction of the evaporator. The pressure drop of the liquid line would be approx 25 kPa, whereas the pressure drop of the hot gas bypass line would be practically 0 kPa. Assuming a mass flow rate of 10 kg/s at node 1, what would be the mass flow rate going into each pipe?
