Answer :
Final answer:
The pressure drop in a capillary tube is influenced by the geometry and resistance of the tube, as represented by the equation P₂ - P₁ = RQ, where narrower sections create more resistance and cause a greater pressure drop.
Explanation:
The pressure drop between the condenser and evaporator in a capillary tube is determined by factors such as the velocity and losses throughout the piping system. In more complex systems, resistance due to varying tube radius plays a crucial role in pressure drops. Narrow places like capillaries experience higher resistance, affecting the pressure drop.
The pressure drop between the condenser and evaporator in a capillary tube is determined by the velocity of the refrigerant, the geometry of the system, and the resistance to flow. Narrower sections of the tube present a greater resistance, much like how plaques in an artery can cause a pressure drop due to obstruction and turbulence.
This concept of fluid dynamics is represented in the equation P₂ - P₁ = RQ, where R represents resistance to flow and Q is the flow rate. The capillary rise phenomenon, affected by tube diameter and surface tension, further exemplifies how the properties and dimensions of a tube can influence the fluid dynamics within it.
