The approximate minimum stream velocity needed to keep a particle in motion, such as a sphere with a diameter of 10 cm, can be estimated using Stokes' law and the concept of terminal velocity. For a particle in a fluid, the minimum velocity needed to keep it suspended typically equals the settling velocity, which depends on factors like fluid density and viscosity. In general, for a 10 cm diameter particle, the minimum velocity can range from about 0.1 to 0.5 meters per second, depending on the specific fluid properties.
It depends on the cable. 0 to 5000 volts the minimum bending radius is 6 x diameter of the cable. Above 5000 volts the minimum bending radius is 8 x the diameter of the cable.
-- Every circle has a diameter of some size. -- All of the diameters that you can draw in the same circle are the same size. -- The smaller the circle is, the smaller its diameter is. There's no minimum size. -- The larger the circle is, the larger its diameter is. There's no maximum size.
4 times the diameter of the cable

you need to figure out how much water per minute you need and get the minimum pipe diameter that will give you that. the bigger they are the more expensive they are, on a logaritmic scale.

The approximate minimum stream velocity needed to move a particle with a diameter of 6.4 can be determined using the equation for the critical velocity of sediment transport. For a particle of this size, the critical velocity is typically around 0.3-0.4 m/s in most natural streams and rivers.
The minimum stream velocity needed to keep a particle in motion can be estimated using the settling velocity equation. For a 10 cm diameter particle, the approximate minimum stream velocity would need to be around 0.03 m/s to keep it in motion. This value may vary depending on factors such as particle density and fluid properties.

The minimum stream velocity needed to keep a 6.4 cm diameter particle in motion is dependent on factors such as the density of the particle and the fluid, as well as other environmental conditions. However, as a general guideline, the velocity required can be estimated to be around 2-3 cm/s for particles of this size.

The minimum velocity required to transport particles with a diameter of 0.04 in a stream is known as the critical velocity. It can be calculated using the Shields criterion, which takes into account the particle size, density, and fluid properties. The critical velocity is the velocity needed to start moving the particle and overcoming the forces acting on it due to gravity and drag.
The instantaneous acceleration of the particle is equal to 0 when the velocity of the particle is at a maximum or minimum. This occurs at the points on the graph where the slope of the velocity-time graph is horizontal or the velocity reaches a peak or trough.
The minimum stream velocity needed to carry a particle of sand depends on the size and weight of the sand particle, as well as the characteristics of the stream such as flow rate and turbulence. In general, for typical sand particles, a stream velocity of around 0.3 m/s to 1 m/s is needed to entrain and transport them.

The approximate escape velocity from Earth is about 11.2 kilometers per second (25,000 miles per hour). This is the minimum speed an object must reach to break free from Earth's gravitational pull and enter into space.
The minimum rate of flow required to maintain the transportation of 1.0 centimeter diameter particles in water is typically around 0.15 meters per second. This is based on the Shields criterion, which determines the threshold for sediment movement in streams based on flow velocity and particle size.
