Advanced Al-Li alloys offer improved specific fracture toughness and fatigue properties, offering customers potential savings in fuel and
maintainance costs.
5000 series Al-alloys are expected to see wide use in future airframes due to improved corrosion resistance.
Aircraft manufacturers are considering applications of advanced Al-Li alloys because they offer increased specific stiffness compared to
conventional aluminium alloys.
Airframe manufacturers are seeking alloys that offer improved corrosion resistance mainly because this allows significant weight savings and
therefore a reduction in fuel costs.
Advanced Al-Li alloys offer an order magnitude increase in strength compared to current alloys, so are a competitive material for wing skins in
future civil aircraft.
Airframe manufacturers are seeking alloys that offer improved corrosion resistance because this offers airlines the benefit of reduced
maintainance costs.

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?
