A wet polyester fabric has areal density of 160 g/m². The initial temperature of the wet fabric is 20°C. After it is completely dried on a cylinder dryer, its areal density drops to 100 g/m².
Consider,
  • Specific heat of polyester as 2.0 J/g °C
  • Specific heat of water as 4.2 J/g °C
  • Latent heat of evaporation of water as 2260 kJ/kg
Assuming that there is no heat loss, the energy (kJ) required to dry 1 m² of the fabric (rounded off to 2 decimal places) is __________.
