Extraction turbine

Back-pressure turbine

Condensing turbine

Answers A and B

It satisfies indoor ventilation rates by preconditioning outdoor air with the exhaust air to decrease energy cost during cold, warm, or humid weather

It's a prescriptive procedure in which outdoor air intake rates are calculated based on the energy cost method that compares a proposed building design to a base annual energy cost design

It's a building standard for enclosed spaces in which biological, chemical, and physical contaminants are considered to meet thermal comfort requirements

It's an active evaluation of outdoor and indoor space conditions to determine the amount of thermal, mechanical and natural conditioning that is required

Raise the supply air pressure

Install a receiver tank near the remote load experiencing low pressure

Decrease the distribution pipe size to the remote load experiencing low pressure

Answers B and C

The motor is operating at high efficiency

The motor is oversized and may be downsized to increase efficiency

The applied voltage is too low and should be increased to improve efficiency

The applied voltage is too high and should be reduced to improve efficiency
