Hello Sir,
Good Afternoon.

I have a question in my homework related Heat Transfer lesson. The following below is my question. Please Advice. Thank You

A double-pipe-counter-flow heat exchanger has an overall heat transfer coefficient of 284.K m² when it's new. The hot fluid enters this heat exchanger with a temperature of 93°C and comes out with a temperature of 71°C, while the cold fluid enters with a temperature of 27°C and comes out with a temperature of 38°C. K If during use, there is a fouling factor of Rf = 4x10-4m2. W Count : a. Log Mean Temperatur Difference (ATim) b. The rate of heat transfer when the heat exchanger is new c. The rate of heat transfer when the Heat Exchanger has a buildup of impurities d. Changes in the rate of heat transfer due to use Tein Thin Thout Te.out C,out
