A process current is used with river water in a body and pipe type heat exchanger from temperature T1 to temperature T2 it is being cooled. Anti-pollution, as pollutants in river water cause shell formation problems chemical (ASC) should be used. The amount of chemicals required according to the outlet temperature of river water it was determined experimentally as given below. The chemical cost is $2000/kg. The cost of pumping it is directly proportional to the amount of water supplied. The cost of pumping river water per year for the outlet temperature of 40C It is 1500S. Determine the objective function and the optimal outlet temperature of the river water
