Question

Which scaling device is powered by an air compressor?

Answer 1

The scaling device powered by an air compressor referred to in the question is commonly used in scuba diving for breathing underwater and in aircraft for measuring airspeed.

Step-by-step explanation:

The scaling device powered by an air compressor is often used in various engineering and technical applications. For example, in the context of scuba diving, compressed air is critical for breathing underwater. Divers carry tanks filled with compressed air, which is delivered through a regulator, allowing them to breathe while exploring marine environments. where scuba divers are shown using compressed air to breathe underwater.

The same principle of utilizing pressurized air is employed for measuring fluid velocities, as mentioned in Figure 12.7(b), which describes a device's application in airspeed indicators for aircraft. These applications demonstrate how compressed air is essential in different engineering contexts for various devices, including those for underwater breathing and airspeed measurements.
