Problem 85HP
Turbines, Compressors, Expanders
Acompressor receives 0.05 kg/s R-410a at 200 kPa, −20°C and 0.1 kg/s R-410a at 400 kPa, 0°C. The exit flow is at 1000 kPa, 60°C, as shown in Fig. P4.85Assume it is adiabatic, neglect kinetic energies, and find the required power input.

ANSWER:
Solution 85 HP:
Step 1 of 2:-
Here we have to power input required.
The receiving of the compressor is,
.
The other input mass flux is,
.
The output mass flux is,
.
The R-410a is at a temperature of at 400 kPa.
The exit flow temperature and pressure are and 1000 kPa respectively.
