position of water tank : water tank is placed at high position, the different in height between water and water tap produce high water pressure, water flows at high speed when the water tap is turned on, position of intravenous liquid: bag of intravenous is placed at position higher than body of the patient, the pressure due to different in height of liquid will push the intravenous liquid into body of patient, the rate of flow of intravenous liquid into the patient body depend on the height of the bag and can be controlled, construction of a dam: the wall of a dam is build thicker at the base, water pressure is increase as depth increase between dam, the thicker section of the dam is able to withstand high pressure, the penstock is lower section to produce high pressure of water to drive the turbines, use of the siphon: water can be transfer using siphon, end tube filled with water is placed in the tank of water at high position while other end at lower position, the flow of water is from high pressure to low pressure of the siphon , atmospheric pressure pushes water from high pressure end of siphon,
