Increases then decreases.
Increases.
Decreases.
Decreases then increases.

Answer 1

As the flow rate of a fluid in a turbomachine increases, the machine efficiency decreases.Therefore, the correct answer is Decreases.

Step-by-step explanation:

In general, as the flow rate of a fluid in a turbomachine increases, the machine efficiency decreases.

This can be explained by the fact that as the flow rate increases, there is more friction and turbulence within the machine, which leads to energy losses and decreases the efficiency.

Additionally, increased flow rate can also result in greater pressure differences and backflow, further reducing efficiency.

Therefore, the correct answer is Decreases.
