In summary, the problem involves determining the power required for a sump pump that moves 20 gallons per minute from a basement to a storm drain 6 feet above. The pump is assumed to be 100% efficient and changes in kinetic energy can be ignored. The equation for power can be rewritten as Power= Force x Velocity, but other formulas for energy may also be relevant. Further guidance is needed to solve the problem.

1. Homework Statement

A sump pump moves 20 gal/min of water from a basement of a building to storm drain 6ft above. Determine the power required for the pump. (Assume the pump is 100% efficient and that changes in kinetic energy are negligible.)


2. Homework Equations
Power= Work x Time
Kinetic Energy=1/2mV^2

3. The Attempt at a Solution
The equation can be re-written as Power= Force x Velocity but I am unsure of how to continue with this problem. Any help getting me on the right track would be very appreciated.

This is clearly homework, so shouldn't be posted here.

Anyway, I'm not sure where you got Power = work x time from; that is incorrect so that won't help your working. Also, the question says that changes in kinetic energy can be assumed to be negligible, so do you know any other formulae for energy which may be relevant here?
 

FAQ: Power of a Sump Pump Moving 20 Gal/min

What is the purpose of a sump pump?

A sump pump is a device that is used to remove excess water from a basement, crawl space, or other low-lying areas of a home. It helps to prevent flooding and water damage by collecting water in a sump basin and then pumping it out and away from the home.

How much water can a sump pump move per minute?

The amount of water a sump pump can move per minute depends on its horsepower and the head pressure. On average, a sump pump can move between 20-30 gallons per minute. It is important to choose a sump pump with the appropriate horsepower for your specific needs.

What is the significance of a sump pump moving 20 gallons per minute?

The rate at which a sump pump can move water is important because it determines how quickly excess water can be removed from an area. If a sump pump can only move 20 gallons per minute, it may not be able to keep up with heavy rainfall or flooding, which could lead to water damage.

How does a sump pump help to prevent basement flooding?

A sump pump helps to prevent basement flooding by automatically removing excess water from the area. When water enters the sump basin, the pump is triggered and begins to move the water out and away from the home. This helps to keep the basement dry and prevent damage to belongings and the structure of the home.

Is it necessary to have a sump pump that can move 20 gallons per minute?

The rate at which a sump pump can move water is dependent on the specific needs of your home. If you live in an area with heavy rainfall or frequent flooding, a sump pump that can move 20 gallons per minute may not be sufficient. It is important to consult with a professional to determine the appropriate size and capacity for your sump pump to effectively prevent flooding and water damage.
