Introducing a metallic rod into an electric field. an uncharged thin metallic rod is introduced into a uniform electrostatic field, of intensity vector eo, in free space, such that it is either perpendicular or parallel to eo, as indicated in fig. q1.15. the rod affects the original field (a) less in case (a). (b) less in case (b) (c) equally noticeably in both cases. (d) negligibly in both cases. eo figure q1.15 introducing an uncharged thin metallic rod into a uniform electric field (eo denotes the original field intensity vector, before a new electrostatic state is established); for question 1.21.

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?
