A counterflow, concentric tube heat exchanger used for engine cooling has been in service for an extended period of time. The heat transfer surface area of the exchanger is 5 m2 , and the design value of the overall convection coefficient is 38 W/m2 ! K. During a test run, engine oil flowing at 0.1 kg/s is cooled from 110(C to 66(C by water supplied at a temperature of 25(C and a flow rate of 0.2 kg/s. Determine whether fouling has occurred during the service period. If so, calculate the fouling factor, .
