Influence of volume fraction of copper nanoparticles on the thermal performance of anautomotive car radiator

The use of mono-type nanofluids in AC systems has gained attention for enhancing thermal conductivity and heat transfer properties, resulting in improved cooling performance.

copper pipe of diameter 3.5 cm and wall thickness 4 mm is used in an antibiotic factory toconvey hot water a distance of 60 m. The inlet temperature of the water is 90°C. Due to heatlosses to the atmosphere, the outlet water temperature is 84°C. The ambient temperature is25°C. The inside of the pipe is covered with a layer of fouling with heat transfer coefficient7500 W m-2 K-1 . The rate of heat loss is estimated as 503 kW.(a) What proportion of the total resistance to heat transfer is provided by the fouling layer?

The heat of evaporation of copper at its normal boiling point is 74.5 kcal/mole (311.71 kJ/mol). The vapour pressure of copper at 1500°C (1773 K) is 0.256 mm Hg (34 N/m ) . Calculate the boiling point of copper.
