The daily maintenance for stations 1, 2, and 3 consumes 10%, 14%, and 12%, respectively,
of the maximum 480 minutes available for each station each day. Determine the optimal
product mix that will minimize the idle (or unused) times in the three workstations.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
