$9.$ True$/$False: Trickle bed reactors are advantageous due to their high energy consumption compared to other reactor types.

$10.$ True$/$False: Flow regime identification is not critical when designing multiphase flow systems.

$12.$ True$/$False: The drift velocity in the drift flux model represents the velocity of the liquid phase relative to the pipe walls.

$13.$True or False: ASTM distillation tests are conducted at standard atmospheric pressure to assess the boiling range of crude oil, providing critical data for refining operations.
