Problem 44P

Problem 44P

Air enters the compressor of a Brayton refrigeration cycle at 100 kPa, 270 K. The compressor pressure ratio is 3, and the temperature at the turbine inlet is 315 K. The compressor and turbine have isentropic efficiencies of 82% and 85%, respectively. Determine the

(a) net work input, per unit mass of air flow, in kJ/kg.

(b) exergy accounting of the net power input, in kJ per kg of air flowing. Discuss.

Let T0 = 315 K.

Step-by-Step Solution:
Step 1 of 3

Operation management ● development and administration of the activities involved in transforming resources into goods and services ● the “core” of most organizations ● emphasis on viewing operations function as a whole ● manufacturing/production = activities and processes used in making tangible goods ● operations (providing a service) = activities and processes used in making both tangible and intangible products Transformation Processes ● inputs = the resources (labor, materials, energy) that are converted into outputs ● outputs = the goods, services, and ideas that result from the conversion of inputs In Service Business ● 70% of all employment in the US… fastest growth market for jobs ● over 72% of GDP in US ● servi
