Andrew is the manager of a factory. Workers at the factory are assigned to one of two tasks, one of which requires skilled labor and one of which
requires unskilled labor. Because skilled workers earn a higher wage than unskilled workers, everyone who applies for a job says they're skilled.
Andrew's challenge is to figure out who is actually a skilled worker and who is an unskilled worker.
Suppose that Andrew would like to use the economic concept of screening to separate out worker types.
Which of the following scenarios illustrates this concept?
A. Skilled workers pay to take a certification course to demonstrate their ability.
B. Andrew implements a test to determine whether applicants are skilled or not.
C. Andrew voluntarily pays all workers a higher wage in hopes of attracting and retaining more productive workers.
Suppose, instead, the manager considers paying efficiency wages to increase the factory's profitability.
True or False: Efficiency wages are higher-than-average wages that are intended to reduce the chances that workers engage in non-productive
behavior that might jeopardize their high-paying job.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
