Question 1Motor Plants - Assistant Engineer

The correct answer is A) 4500 kg-meters per minute = 1 HP. This is because 1 horsepower (HP) is equivalent to 33,000 foot-pounds per minute in the imperial system. To convert this to the metric system of kg-meters per minute, we need to use the conversion factor of 1 foot-pound = 0.1383 kg-meter. Applying this conversion factor, we get 33,000 ft-lbs/min x 0.1383 kg-m/ft-lb = 4,564 kg-m/min, which rounds to 4,500 kg-m/min = 1 HP. The other answer choices are incorrect because they do not accurately reflect the conversion from the imperial system to the metric system based on the given information.
