Focus on Compressed Air Question Title * 1. In a system with multiple compressors, what is the best metric for overall system energy efficiency? Total kW/h used Total kW of all compressors running at 100% The combined specific performance of all compressors in the system OK Question Title * 2. Air compressors typically reject approximately how many BTU/hr for every hp? 10,000 2,000 1,000 5,000 OK Question Title * 3. Which item is NOT a negative result caused by oversizing an air compressor? High electrical costs High maintenance costs Moisture damage caused by short cycling and not reaching operating temperature Short equipment life Low air pressure downstream OK Question Title * 4. How much of compressor input power is converted to waste heat that could be recovered for other uses? 10% 33% 65% over 95% OK Question Title * 5. Which of the following dryer types may not always require a pre-filter? Refrigerant dryer Desiccant dryer Deliquescent dryer All the options are correct OK Question Title * 6. When sizing a refrigerated dryer, which of the following is NOT a critical factor to consider in the calculation? Inlet air pressure to the dryer Ambient-air relative humidity Inlet air temperature to the dryer Ambient air temperature Amount of air the dryer must be able to dry (scfm or flow) OK Question Title * 7. The pressure loss through 1,000 ft of smooth 2-in. diameter pipe is 16 psig for 500 cfm at 125 psig.
