Question

Had me second guessing the knowledge I have. Just stay calm and think about system and operations to help you find the answer.

The answer to number 4 seems like a contradiction

B

D

question 17, This is incorrect. The flow rate is constant regardless of working pressure of a fixed displacement pump. Look, Yes the flow rate would drop due to rotor slip of a motor but this is NOT calculated for in this level of testing. If you don't know what rotor slip is, or are not designing a system to land on the moon, you are not calculating for slip and this is just leading people down the wrong path because this exam is going to be expecting them to be saying that the answer is constant. This is just messing with people trying to learn.

some of these are absolutely incorrect

D
