An oil emulsion having 15% water cut by weight is being treated in a horizontal heater-treater unit at the rate of 6000 kg/hr. The inlet temperature of the emulsion is 30°C and operating temperature of the heater-treater is 40°C. The specific heat capacity of water and oil are 1 kcal/kg°C and 0.5 kcal/kg°C, respectively. Assuming 10% of the total heat input is lost to the surroundings, the total heat energy required to break the emulsion in the heater-treater unit is ______ kcal/hr. (write answer with one decimal place)
