Which of the following is a consequence of improper sizing of air compressors in pneumatic systems?

Improper sizing of air compressors in pneumatic systems leads to higher energy costs and reduced system performance due to several factors. When a compressor is undersized, it cannot produce enough air to meet the demand of the system, which can result in inadequate performance of pneumatic tools and devices. This can cause the system to run continuously at a higher capacity, leading to increased wear and tear on components, further elevating operational costs.

Conversely, an oversized compressor may cycle on and off frequently, which wastes energy and can lead to inefficiencies. Additionally, energy is wasted not just in operating the compressor but also in maintaining pressure levels and managing the resulting heat generated by excessive idle running. Thus, maintaining the right size of the air compressor is crucial for optimizing energy use and ensuring that pneumatic systems operate efficiently and effectively.
