Mango pulp at an initial temperature of 25 °C and a moisture content of 70% (wb) is to be dried into leather to a final moisture content of 10% (wb) using hot air at 95 °C. The latent heat of vaporization of water at 95 °C and at standard atmospheric pressure is 2250 kJ.kg⁻¹. Considering the specific heat of mango pulp as 3.8 kJ.kg⁻¹.°C⁻¹, the energy required for drying per kg of mango pulp, in kJ, is _______. (Rounded off to 1 decimal place)
