Types of Step-Growth Polymers: Polyesters

Types of Step-Growth Polymers: Polyesters

The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...

Molecular Weight of Step-Growth Polymers

Molecular Weight of Step-Growth Polymers

Step growth polymerization involves bi or multifunctional monomers. Bifunctional monomers react to form linear step growth polymers, whereas multifunctional monomers react to form non-linear or branched polymers.
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
The extent of the...

Free Jet

Free Jet

Free jets describe the flow of liquid exiting a reservoir through an opening into the atmosphere without resistance. The velocity (v) of the liquid jet is derived using Bernoulli's principle and expressed as:

Background:

Liquid jet pumps are vital for industrial fluid handling but suffer from lower efficiency compared to other pump types.
Energy dissipation during the entrainment process is the primary cause of reduced efficiency in liquid jet pumps.
Key performance factors include motive fluid pressure, nozzle design, and entrainment ratio.

Purpose of the Study:

To investigate a novel method for enhancing the efficiency of liquid jet pumps.
To assess the impact of drag-reducing polymers (DRPs) on liquid jet pump performance.
To evaluate the effectiveness of DRPs using established efficiency models.

Main Methods:

Implementation of a water-water loop system with a liquid jet pump.
Introduction of drag-reducing polymers (DRPs) into the suction flow of the jet pump.
Evaluation of efficiency improvements using various literature-based models.

Main Results:

A specific configuration of DRPs led to a significant reduction in drag within the liquid jet pump.
Pump efficiency increased from 13.8% to 26.7%, representing a 46% drag reduction.
Overall pump performance was substantially improved by the DRPs.

Conclusions:

Drag-reducing polymers offer a viable solution to enhance liquid jet pump efficiency.
The integration of DRPs can overcome the inherent limitations of jet pump energy dissipation.
A new interpretation of jet pump efficiency and a comparative analysis were presented.
