Consider a paged-segmentation memory-management scheme that allows up to 8 segments per process, laid out over pages of size 16KB.
Let the segment sizes of three processes P1, P2 and P3 be as follows:
Process Segment Number Segment Size
P1 0 81KB
P1 1 116KB
P1 2 32KB
P2 0 48KB
P2 1 60KB
P2 2 200KB
P2 3 142KB
P3 0 146KB
P3 1 72KB
Compute the internal fragmentation for each segment, and determine the total internal fragmentation for each process. Based on this computation, identify the TRUE statement among the following?
A. Only one out of the three segments of P1 has internal fragmentation. B. All the segments of P2 have internal fragmentation. C. All the segments of P1 have internal fragmentation. D. All the segments of P3 have internal fragmentation

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?
