Is There a Relationship Between The Ideal Carnot Cycle and The Actual Vapor Compression Cycle? Delmar Ray Riffe Americold ABSTRACT Historically the Carnot cycle has been accepted as a reference point for comparison in the design and evaluation of engines and similarly the “reversed” Carnot cycle has been accepted as a reference point for comparison in the design and evaluation of refrigeration
The flow of ideal fluids can be rotational by external work or heat interaction. Laminar or Turbulent Flow. Laminar Flow. The flow of a fluid moving with a moderate speed has fluid layers moving past other layers as if some sheets are moving over other layers. Such flow of fluids is called Laminar Flow. In Laminar Flow viscous shear stresses act between these layers of the fluid which defines

analogy to the increased pressure of an ideal gas with temperature. Ceramic aggregates show a weak temperature dependence with lowered modulus with higher temperature. A major difference between polymer coils and ceramic aggregates is the “adaptability” of a polymer coil to external and internal forces. Adaptability for a polymer coil at thermal equilibrium means that the uniform mass-size

Though the ideal self is present, which is the ultimate goal and a motivator to perform, there is no clash between the real and the ideal self. As long as the real self means moving towards positive growth, it should be encouraged.
In contrast, ideal fluids only respond with restoring forces to normal stresses, called pressure: fluids can be subjected to both compressive stress, corresponding to positive pressure, and to tensile stress, corresponding to negative pressure.
The difference between hydraulics and pneumatics is the medium used in each system to perform work. Hydraulics employ fluids, such as oils, while pneumatics utilize compressed gases, such as carbon dioxide or atmospheric air.

Knowing the difference between ideal and real is necessary since ideal and real are two states that need differentiation in terms of their meanings and connotations. Ideal is something that is more suited for a given purpose. Real is something that is permanent. Looking at these two words, ideal and real, from a linguistics point of view one can see that real is used as an

Download Presentation & View Webinar Recording. Flow behavior of complex fluids is traditionally characterized through the distinction between Newtonian and non-Newtonian based on each fluid’s viscosity dependence on the rate of deformation and the rate of shear rate.
These are the main points of difference between an ideal gas and a real gas. For a real gas, all these points are not valid, therefore: Gas particles occupy a space and therefore have a volume. Gas particles collide with each other and their motion tends to speed up or …
It is said that an ideal fluid has a zero viscosity, while a real fluid has a non-zero one. However, in reality, there is no such thing as “ideal fluid”, because a fluid with zero viscosity does not exist. Thus, every fluid is real, with no exepction.

where U is the overall heat transfer coefficient, ΔT is the local temperature difference between the hot and cold fluids, and dA is the contact area in the differential segment. The overall heat transfer coefficient is inversely proportional to the total resistance R tot to the heat flow. The latter is the sum of (1) resistance R conv,h to convective heat transfer from the hot fluid to the

A voltage source is a two terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage , whatever be the load resistance or the output current i.e. an ideal voltage source supplies constant voltage to a circuit despite the current which the circuit draws.
The flow between these two streamlines carries the same mass flow/span at each cross-section, and can be considered as a 2-D channel flow embedded in the rest of the flowfield.

All the fluids in reality have viscosity (μ > 0) and hence they are termed as real fluid and their motion is known as viscous flow. Under certain situations of very high velocity flow of viscous fluids, an accurate analysis of flow field away from a solid surface can be made from the ideal flow theory.

relation between the shear stress and the rate of deformation of the fluid. • Fluids for which the shear stress is directly proportional to the rate of deformation are know as Newtonian fluids. • Engineering fluids are mostly Newtonian. Examples are water, refrigerants and hydrocarbon fluids (e.g., propane). • Examples of non-Newtonian fluids include toothpaste, ketchup, and some paints
the absolute pressure is the difference between the pressure at a given point in a fluid and the absolute zero of pressure or a perfect vacuum. the fluid is much smaller than the pressure being applied to the system. However, this may not remain true if the system is large enough or the pressures low enough. One example considers how atmospheric pressu re changes with altitude. At sea
Properties of Fluids attractive forces between the molecules of a solid are so large that a solid tends to retain its shape. This is not the case for a fluid, where the attractive forces be- tween the molecules are smaller. An ideal elastic solid will deform under load and, once the load is removed, will return to its original state. Some solids are plastic. These deform under the action

The behavior of a real gas approximates that of an ideal gas as the pressure approaches zero. The effects of non-ideal behavior are best seen when the PV product is plotted as a function of P . You should be able to identify the regions of such a plot in which attractive and repulsive forces dominate.
The main difference between an ideal fluid and a real fluid is that for ideal flow p 1 = p 2 and for real flow p 1 > p 2. Ideal fluid is incompressible and has no viscosity. Real fluid has viscosity. Ideal fluid is only an imaginary fluid as all fluids that exist have some viscosity.
