When a positive displacement pump runs dry, it can lead to several issues, including overheating and damage to the pump components due to lack of lubrication and cooling provided by the fluid. The absence of liquid can cause the pump to experience excessive wear, cavitation, or even mechanical failure. Additionally, if the pump is not equipped with any protective measures, such as a thermal shutdown or pressure relief system, it may sustain irreversible damage, leading to costly repairs or replacement. Regular monitoring and maintenance are essential to prevent such situations.

What happens to the fuel pump in a 1993 corvette if it runs out of gas?

The fuel pump is located in the fuel tank and is cooled by the fuel. If you ran out of gas it could cause the fuel pump to overheat and burn out.


What is the total displacement of a dog that runs 80 meters to chase a ball returns to its master and the runs south 20 meters?

To find the total displacement, we consider the dog’s initial and final positions. The dog runs 80 meters to chase the ball and then returns 80 meters back to its starting point, resulting in no net displacement from that segment. Finally, when the dog runs 20 meters south, the total displacement is 20 meters to the south. Thus, the total displacement is 20 meters south.

Which is the total displacement a dog that runs north 80 meters to chase a ball return to its master and then runs south 20 meters?

To calculate the total displacement of the dog, we consider its starting point as the origin. The dog runs 80 meters north, then returns to its master (which we can assume is at the starting point), and finally runs 20 meters south. Therefore, the total displacement is 80 meters north - 20 meters south, resulting in a net displacement of 60 meters north.


What happens if for whatever reason the water level drops and your pool pump runs without water for over 4 hours?

If water does not flow through your pump while the pump is operating the pump will "loose prime" what remaining water in the pump will boil from the friction of the impellor spinning, this will turn the water to steam and melt the plastic parts. Also known as the pump has "Dry Run"

What happens to a car when you put in the wrong battery size?

I was told if the battery is "insufficient" it makes the starter crank slower, the fuel pump pump slower and hence ruins the car. I think that's a bunch of hooey b/c once started, the car runs off the alternator. Nevertheless, my freind believed the mechanic who charged him $1500. for a new battery, starter, fuel pump and other crazy things he mentioned but I just cannot remember. My advice is, hook the terminals to the correct wire (positive/negative) and fire it up!
