Final answer:
Oil pressure should be within the range specified by the manufacturer's specifications, usually between 20 to 30 psi at idle and up to 60 psi under load. It's important to consider additional factors such as temperature, oil viscosity, and any additional pressure from an oil column when determining the correct operating pressure.
Step-by-step explanation:
The oil pressure during operation should be determined based on the specific requirements of the machinery and the type of oil being used. For many vehicles, a common range might be between 20 to 30 psi at idle and up to 60 psi under full load conditions. It's important to consult the manufacturer's specifications for the precise range appropriate for the equipment or vehicle in question. Additionally, environmental factors, such as temperature and oil viscosity, can also affect the necessary oil pressure. For example, colder temperatures may require higher pressure to ensure proper lubrication. Using the given information, one would also have to take into account the pressure added by a 50.0-m column of oil, which could significantly affect the overall pressure within a system.
