If the total investment cost of a plant producing sugar is $1.2 million and the raw materials and other services are estimated as :
steam 207kg/hr at $2/kg of steam
cooling water 6500kg/hr at $2.5 per kg of water
electrical power 3500kwh/day(360mj at $1.5/kwh). and if plant attainment is 92%, calculate the annual operating cost
