What is the U-factor of a heat exchanger?
In the analysis of heat exchangers, it is often convenient to work with an overall heat transfer coefficient, known as a U-factor. The U-factor is defined by an expression analogous to Newton’s law of cooling.

What is the exchange particle for the strong force?
The pionwas initially considered to be the exchange particle for the strong force because it fitted with the quark exchange involved but that has now been amended in the light of recent work and the exchange particle for the strong force is now known as the gluon. This is an illustration of how examination boards adapt to new findings….

What is the steady state flow of a heat exchanger?
Steady state flow is a valid assumption for steady operating conditions and temperatures. The figure below shows a schematic of a parallel-flow heat exchanger along with temperature distribution for the hot and cold fluids. We treat the heat exchanger as insulated around the outside so that the only heat transfer is between the two fluids.

What is the exchange particle responsible for the electromagnetic force?
The photon is the exchange particle responsible for the electromagnetic force. The force between two electrons can be visualized in terms of a Feynman diagram as shown below. The infinite range of the electromagnetic force is owed to the zero rest mass of the photon.

How does a heat exchanger work in a car?
The classic example of a heat exchanger is found in an internal combustion engine in which an engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. When compared to shell and tube exchangers, the stacked-plate arrangement typically has lower volume and cost.
What are the characteristics of a heat exchanger tube?
The tubes may be straight or bent in the shape of a U, called U-tubes. Tube diameter: Using a small tube diameter makes the heat exchanger both economical and compact. Tube thickness: The thickness of the wall of the tubes is usually determined to ensure: There is enough room for corrosion

How does the exchange of particles affect the volume of matter?
This interaction increases (for fermions) or decreases (for bosons) the expectation value of the distance between identical particles (compared to distinguishable particles). Among other consequences, the exchange interaction is responsible for ferromagnetism and the volume of matter.
