   Tests rocket engine design basics: how thrust, chamber pressure, mixture ratio and nozzle expansion set engine size.

3. 03

   You are shown the BE-3 engine. Which turbopump is for fuel and which for oxidizer, and why does each need a separate shaft and turbine when other engines use one common shaft for both?

   Tests turbomachinery layout: why fuel and oxidizer pumps get separate shafts and turbines, such as speed and drive trade-offs.

4. 04

   What options are there to measure flow rate, and when and why would you use each one?
