Ben is designing a pasteurisation process for his new electrically powered dairy plant. The plant will use an electrode boiler (boiler powered by electricity) to supply saturated steam at 5 bar to heat up the milk from 4C to 72C. On average, the dairy plant will operate for 6000 hours each year. Ben wants to know how much electricity he will use per year for this heating process and how much it will cost if the power of electricity is $0.09/kWh and the efficiency of his electrode boiler is almost 100%. Take the density of milk to be 1035 kg/m?. Steam from boiler 5 bar Saturated vapour Milk 4C 20 L/S 1035 kg/m Pasteurising section 72C
