How to Answer
Display to the hiring manager that you are able to explain basic concepts in a simple to understand manner. Your answer should be concise but accurate.

Answer Example
"Yes, I can tell the difference between Induced Draft and Forced Draft. Induced Draft (ID) is when a fan is used to extract the air from a boiler post combustion via Electrostatic Precipitator to exhaust through the chimney. Forced draft (FD) is when a fan is used to force air into the boiler to provide more air for combustion."

Explain to me why some cooling towers are 300 feet tall, and others look like a 30 by 30 foot cubicle on top of a building?
Professional Answers Preview
How to Answer
Display to the hiring manager that you are able to explain basic concepts in a simple to understand manner. Your answer should be concise but accurate.

Answer Example
"The size of the cooling tower will depend greatly on the type of application the cooling tower is meant for. Facilities such as power plants, steel processing plants, petroleum refineries, or petrochemical plants usually install field erected type cooling towers due to their greater capacity for heat rejection. Field erected towers are usually much larger in size compared to the package type cooling towers."
