Spiritual gifts are not innate, natural talents, like an ear for music or the ability to draw, but rather they are empowerments that the Holy Spirit gives to a believer to minister to the body in ways that were not possible by mere natural effort apart from the Holy Spirit.
In the design of a dam, the first step is the determination of various forces which acts on the structure and study their nature. Depending upon the situation, the dam is subjected to the following forces: 1. Water pressure. 2. Earthquake forces. 3. Silt pressure. 4. Wave pressure. 5. Ice pressure. 6.
Dams block the flow of a river or stream and create a lake or reservoir behind them, which acts as a source of stored energy (a battery is another example of a reservoir of stored energy). The dam raises the surface water up to a great height, giving it potential energy, the potential to do work.Water flows from the reservoir and through a dam by way of a special intake gate called a penstock. It's kind of like one of those water tunnels you slide through at a water park in the summer. Water flow rate is in cubic meters per second (m 3 /s). 2  Acceleration due to gravity is 9.81 meters per second squared (m/s 2). 3  Height is in meters (m). 4  Coefficient of efficiency ranges from 0 to 1, with modern power plants having the highest efficiency.
