question
From economy considerations, suggest the use of either aluminium alloy or copper alloy fins. The following data is given: Density of the aluminium alloy = 2400 kg/m^3 Density of the copper allow = 8400 kg/m^3 Conductivity of the aluminium alloy = 78 kCal/m-hr°C Conductivity of the copper alloy = 190 kCal/m-hr°C The cost of aluminium alloy is twice the cost of copper alloy.
category
engineering
options
- copper alloy for the core structure, with aluminium alloy as a decorative finish
- aluminium alloy for low-temperature applications, copper alloy for high-temperature applications
- copper alloy
- aluminium alloy, but with increased thickness to match copper alloy performance
- a composite material that blends both aluminium and copper alloys
- equal amount of both alloys
- copper alloy with a coating of aluminium for enhanced conductivity
- alternating layers of aluminium and copper alloys
- neither alloy
- aluminium alloy
