A pump that is moving water up a tower has a power rating of 400W. How long would it take a molecule of water to travel the height of the tower If it is 91% efficient, and it is moving 80L of water up a height of 20m with a constant velocity?

Step 1
The energy required to lift an object is given by the formula E = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height. The mass of the water can be calculated by multiplying the volume by the density of water. The density of water Show more…
