Inducing a Positive Charge on a Sphere
The given below animation depicts the induction procedure. The neutral conducting sphere is at rest on top of an insulating stand. An unhelpfully charged tube is brought near to (without touching) the neutral sphere. The presence of the negatively charged tube forces electron movement from the left to the right side of the sphere. This movement of electrons is just a reaction to the presence of negative charge such as charges repel. At one touched through the ground, the electrons leave the sphere. While the tube is moved away, there is a whole positive charge left on the sphere.
A concentric tube heat exchanger is comprised of a thin wall inner tube of 25.4 mm diameter and an outer tube of 47 mm diameter. The heat exchanger is used for cooling lubricating
