Final answer:
Without specific context, the normal hydraulic reservoir quantities cannot be definitively answered. Coolant reservoirs in automobiles, however, are tailored to the vehicle's cooling system, with no standard size across different makes and models.
Step-by-step explanation:
The question regarding normal hydraulic reservoir quantities does not have enough context to provide a specific answer; different systems will require different reservoir sizes. However, in the context of the information provided and the multiple choice answers, none of the volumes listed (7 gallons, 11 gallons, 10 gallons, 8 gallons) are directly referenced.
Instead, we have a capacity conversion and estimation exercise, and a more relevant example is given in regards to automobile coolant reservoirs. For example, the coolant reservoir capacity question details the thermal expansion of fluid in a 16-L (approximately 4.23 gallons) capacity radiator.
For coolant reservoirs, there is no standard size, as they are designed based upon the capacity of the vehicle's cooling system, expected expansion volumes, and safety margins. Common coolant reservoir sizes can vary significantly, underscoring the necessity to refer to specific system requirements or manufacturer specifications.
