Answer :
Final answer:
The specified pressure range for the tractor protection valve is 20 to 45 psi. Tire pressure is best measured when cold, and the value on the tire indicates the maximum pressure. Gauge pressure is the pressure reading, absolute pressure includes atmospheric pressure.
The correct answer is 3) 20 to 45 psi.
Explanation:
The pressure range at which the tractor protection valve is designed to close automatically. This is an aspect of vehicle maintenance within the field of engineering. The correct answer to the question of what pressure range is specified by the manufacturer for the tractor protection valve is option 1, which is 20 to 45 psi.
Maintaining correct air pressure in vehicle tires is crucial for vehicle performance. The recommended tire pressure is usually between 32-35 psi and can be found in the owner's manual or inside the vehicle's door. It's important to note that the pressure value listed on the tire is the maximum pressure for that tire, not the recommended pressure.
When measuring tire pressure, it is best done when the tire is cold, as driving heats the tire and increases the pressure. The distinction between gauge pressure and absolute pressure is also essential in understanding vehicle maintenance. Gauge pressure is the reading from a pressure gauge, while absolute pressure is gauge pressure plus atmospheric pressure (14.7 psi).
The correct answer is 3) 20 to 45 psi.
