Water Pump

This is a water pump.We use water pump everday in our lives.In every house in every corner water pums are popular and usefull nowadays.The aim of the water pump is taking out the water from water cans easily into glasses or storage.Water pumps enable us to transfer water without tilting water can.We don’t need to tilt or lift the can.We can easily pump the water by pressing on the water pump.I think this is a very simplified way of transferring water and drinking it easily.Moreover by this way we are gaining more time.It takes less time to pump the water then tilting the can.The negative way of the water pump is that water leaks everytime after the pumping is finished.This means the place can be wet all the time.Another bad way of water pump is its slowness in water transfer.By tilting the can water dumping can ve faster.We can spill  the water in one time into a big store can if we tilt it but by pumping it could be slower.So water pumps have both positive and negative ways but it is certain that it simplifies our life and that is the main goal of designing a water pump.
