liquid engine burn rate

[LouW]

Playing on PS4 with latest update, career mode.

Problem is the rocket engine seems to burn twice as long as it should.

Use a LV-T45 engine with a liquid fuel burn rate of 6.166 units/sec.,  and an oxidizer burn rate of 7.536 units/sec.

Use a FL-T100 fuel tank holding 45 units of liquid fuel, and 55 units of oxidizer.

45 units of liquid fuel divided by 6.166 units/sec = 7.3 second burn time.

55 units of oxidizer divided by 7.536 units/sec = 7.3 second burn time.

The fuel and oxidizer mix and burn together, so the total burn time should be 7.3 seconds.

When I launch the rocket it burn for 14.6 seconds.

Where am I going wrong?

Are you at full throttle? How about a screenshot?

Thrust limit on the engine?

I just tested that in my career and about 7 seconds MET the engine runs out of fuel.

Seems legit

Thanks for the help everyone.  Vanamonde nailed it!  Checked everything I could think of and never looked at the throttle setting. Boy am I a dummy.
