Define the term, “fouling.”
What will be an ideal response?
Fouling- buildup on the internal surfaces of devices such as cooling towers and heat exchangers, resulting in reduced heat transfer and plugging. Fouling also reduces fluid flow In most cases fouling takes place in the tube side of the exchanger, however, it is possible that it could occur in the shell if a large number of support baffles

What will be an ideal response?
Answer the following statement(s) true (T) or false (F)
1. The primary winding of a current transformer must be connected in parallel with the load. 2. When a small amount of AC current must be measured, a CT is connected in the power line. 3. When current transformers are used, the main power line is inserted through the opening in the transformer. 4. To use the clamp-on type of AC ammeter, the jaw of the meter is clamped around all of the conductors supplying power to the load. 5. The ability to change the turns ratio of a clamp-on ammeter can be very useful for measuring low currents.
