Given that the company "slate rock and gravel" has business locations in granitetown and bedrock, suppose that the company has been assigned a large block of consecutive ip addresses starting with 192.172.0.0, and that it wishes to set up two subnets, one for each location, with each subnet having sufficient ip numbers assigned to cover the host computers at that location. the ip addresses must be assigned in this order: first to granitetown, and then to bedrock. assume that there are 4,000 computers in granitetown and 2,000 in bedrock. your task is to assign ip address to the two locations. you must show your steps for each calculation.

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?
