- The wall of the dam is built thicker at the bottom to withstand a higher pressure.
- The generator is placed at the lower part so that the pressure of the water is high enough to drive the turbine.
Measuring Blood Pressure
When measuring blood pressure, the inflatable cuff of the sphygmomanometer should be at the same level with the heart so that the pressure measured is equal to the blood pressure of the heart.
For intravenous transfusion (IV), the bottle is hung at an elevated position to ensure that the liquid in the IV bottle gains sufficient pressure to flow into the vein of the patient.
The water tower is built at high place so that the water has sufficient pressure to flow to consumer’s house.
