# 200kg Water Moved in 1min by 600W Pump

• looi76
In summary, a 600W pump is able to move 200kg of water in 1 minute due to its power and efficiency in converting electrical energy to mechanical energy. This feat is significant in various industries and applications, such as agriculture, construction, and firefighting. The weight of the water being moved does not directly affect the pump's performance, but it does require a more powerful pump. Other factors that can affect a pump's performance include its type, condition, and the type of fluid being pumped. While moving 200kg of water in 1 minute may not be a common feat, it is achievable with a high-quality pump and proper maintenance.

## Homework Statement

A pump with a power output of 600W raises water from a lake through a height of 3.0m and delivers it with a velocity of 6.0 ms^-1. what mass of water is removed from the lake in one minute?

## Homework Equations

Kinetic Energy = 1/2*m*v²

## The Attempt at a Solution

600 = 1/2*M*6.0²
M = 200kg

You can't substitute 600W for the kinetic energy, because energy is measured in joules, not watts. Try and use $$P=F*V_{ave}$$.

I can confirm that the calculation provided is correct. The mass of water removed from the lake in one minute would be 200kg. This calculation is based on the equation for kinetic energy, which takes into account the mass and velocity of an object. In this case, the pump's power output of 600W is used to raise the water through a height of 3.0m and give it a velocity of 6.0 ms^-1. With this information, we can calculate the mass of the water using the formula for kinetic energy. This calculation is important in understanding the efficiency and capabilities of the pump in moving water.

## 1. How is it possible to move 200kg of water in just 1 minute using a 600W pump?

The ability to move such a large amount of water in a short period of time is a result of the pump's power and efficiency. The 600W pump is able to convert electrical energy into mechanical energy, which is used to drive the impeller and move the water. Additionally, the design of the pump allows for maximum flow rate and minimal resistance, allowing for faster movement of water.

## 2. What is the significance of moving 200kg of water in 1 minute?

Moving large amounts of water quickly can be important in various industries and applications. For example, in agriculture, it can be used for irrigation systems to efficiently water crops. In construction, it can be used for dewatering to remove excess water from a site. It can also be used for firefighting, water treatment, and many other purposes.

## 3. How does the weight of the water affect the pump's performance?

The weight of the water being moved does not directly affect the pump's performance. However, it does require more power and energy to move a heavier load, which is why a more powerful pump is needed for 200kg of water compared to a smaller amount. The flow rate and pressure of the water can also be affected by the weight, but this is taken into consideration when selecting the appropriate pump.

## 4. What other factors can affect the performance of a pump?

Aside from the power and efficiency of the pump, other factors that can affect its performance include the type and condition of the pump, the type of fluid being pumped, the distance and elevation of the pump, and the presence of any obstructions or restrictions in the system. Proper maintenance and regular checks are also important to ensure optimal performance.

## 5. Is moving 200kg of water in 1 minute a common feat for a 600W pump?

The ability to move 200kg of water in 1 minute is considered a high flow rate and would require a powerful pump. While it may not be a common feat, it is achievable with a high-quality, well-designed pump. Factors such as the type of pump and the conditions of the system can also affect the pump's performance and its ability to move water at this rate.
