The harrison group life insurance company computes annual policy premiums based on the age the customer turns in the current calendar year. the premium is computed by taking the decade of the customer’s age, adding 15 to it, and multiplying by 20. for example, a 34-year-old would pay $360, which is calculated by adding the decades (3) to 15, and then multiplying by 20. write an application that prompts a user for the current year then a birth year. pass both to a method that calculates and returns the premium amount, and then

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?

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
