Gravity flow is fluid flowing due to the forces of gravity alone and not to an applied pressure head. In the Bernoulli equation, the pressure term is omitted, and the height and velocity terms are the only ones included.

Gravity flow refers to the natural movement of a fluid (such as water) through a pipeline or system due to the force of gravity. It does not require the use of pumps or other external mechanisms to move the fluid. Gravity flow systems are commonly used in irrigation, sewage systems, and water supply networks.
No, gravity does not directly cause rivers to flow. Rivers flow due to the force of gravity pulling the water downstream. The elevation gradient along the river channel allows the water to move from higher to lower elevations, creating the flow of the river.
Electricity is not directly affected by gravity. Gravity does not impact the flow of electricity through wires or circuits.
Gravity flow in IV therapy refers to the natural movement of fluid from a higher position (such as an IV bag hanging above the patient) to a lower position by the force of gravity. This flow rate is controlled by the height of the IV bag and the size of the IV tubing.
Gravity is important for a normal pen because it helps to keep the pen in a downward position, allowing the ink to flow properly onto the paper. Without gravity, the ink may not be able to flow consistently, resulting in poor writing quality.
Life on Earth depends on the interaction of gravity and the atmosphere. Gravity helps to hold the atmosphere in place, which in turn regulates the temperature, provides oxygen, and protects life from harmful radiation.
