I missed most of the VNT questions, because I've never researched them. I also missed the invention date range, because they were so close together. I know that turbos were used in WW1.
I don't like their answer to this question:
2. The turbo derives its energy source from:
A. The temperature of the exhaust gas
B. The pressure of the exhaust gas
C. Both the temperature and pressure of the exhaust gas
D. The engine power
They say it is letter C and I say it is letter B. The temperature is something that can create more pressure. Temperature does not add power, but increased pressure resulting from higher temps will increase power. If you are running the same pressure, but only hotter, do you think it will make more power than someone with less temperature and the same pressure?
If 2 scenarios have the same pressure, but one is hotter, I'd take the cooler one.
Someone help me understand how temperature alone without increasing pressure will make more power.
