What is the primary indication of fouling of a heat exchanger? |
A) A decreased pressure drop associated with the side where the fouling exists and a decreased temperature differential between the two fluids exchanging heat. |
B) A decreased pressure drop associated with the side where the fouling exists and an increased temperature differential between the two fluids exchanging heat. |
C) An increased pressure drop associated with the side where the fouling exists and a decreased temperature differential between the two fluids exchanging heat. |
D) An increased pressure drop associated with the side where the fouling exists and an increased temperature differential between the two fluids exchanging heat. |
