Home depot. you donít have a pickup truck (nor does your friend), but you do have a roof rack with cross bars on your car. so you will have to secure the plywood to the roof rack in order to get it home. your friend (the one who does not have a pickup truck) suggests that you tie the plywood on sideways (so that the short edge is front to back) and drive at about 13 mph. use standard sea-level conditions = 0: 002369 slugs/ft3 and = 3: 7372 107 slugs (a) estimate the drag on the plywood for the case suggested by your friend. (b) estimate the drag on the plywood if you turn the sheet so that the long edge is front to back. (c) explain why your friend suggested the sideways configuration.

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?
