I hope you can follow this okay... I know I can't. It's for school and I'm totally lost. Here's the questions:
Assume that peak torque and horsepower occur at 4000-RPM AND 5700-RPM respectively. Also, assume this enginge has an indicated horsepower of 300 at 5700-RPM.
1. At 5700-RPM, the mechanical efficiency is (A) 10% (B) 75%
(C) 90%
2. The volumetric efficiency is highest at about (A) 1600-RPM
(B) 4000-RPM (C) 5700-RPM.
3. At 5700-RPM, the frictional horsepower is (A) 30 (B) 270
(C) 300
I'm dieing with this question... even if you can only answer one that would be a huge help. Thanks!

I agree with Nomadd, this isn't a math question but a definitions question.
2: The peak of the torque curve tends to follow the peak volumetric efficiency. So the highest volumetric efficiency is at (B) when peak torque occurs.

MEE... i have continually idea that I suck at math becuz i do not attempt. yet when I studied and did better practice 4 a attempt I were given a D. Now i'd ought to repeat pre-algebra back in 9th grade... pray 4 me!!

It's not math that's the problem. None of those questions can be answered with the information given.

1) a
2) ????? not sure on how they want the volume broke down
3)C (300hp@5700rpm)
