What is a potential consequence of leaks in a pneumatic system?

Leaks in a pneumatic system lead to reduced efficiency due to the loss of compressed air. When there is a leak, the system must work harder to maintain the desired pressure levels because the escaping air diminishes the overall air supply. This results in increased energy consumption, which can raise operational costs and lower the overall productivity of the system. Reduced air pressure affects the system's ability to perform tasks efficiently, such as activating cylinders or running pneumatic tools, thereby impacting the reliability and effectiveness of the machinery.

The other options do not accurately describe the consequences of leaks. While a leak might sound like it could lead to increased pressure in some isolated locations, the overall system pressure typically drops due to the loss of air. There is certainly an impact on system performance when leaks occur; they do not enhance control or precision, but rather create inconsistency and unpredictable behavior within the system.
