consider a multiple pump system to meet the design requirements. Two typical options include parallel and series configurations of pumps. Specific performance criteria must be met when considering these options. Given a piping system which has a known design flow rate and head requirements‚ Qdes‚ hdes‚ the following pump selection criteria apply. Pumps in Parallel: Assuming that the pumps are identical‚ each pump must provide the following: Q(pump) = 0.5 Qdes h(pump) = hdes Pumps in Series: Assuming

Through common practise of Centrifugal pump operating characteristics is it possible to determine the optimum conditions of particular conditions. The results of typical characteristics are expressed on this work in terms of pump discharge pressure‚ pump efficiency‚ and power demand at various pump speeds of verses pump discharge.

Compressors are similar to pump‚ both increase the pressure on a fluid and both can transport a pipe. As gases are compressible‚ the compressor also reduces the volume of a gas. Liquids are relatively incompressible‚ while some can be compressed‚ the main action of a pump is to pressurize and transport liquids. Types of compressors The main types of compressors are shown below: Compressor types Positive displacement Dynamic 1. Reciprocating. 2. Rotary 1.Centrifugal. 2. Axial

THE SYMBOLIC SIGNIFICANCE OF SIBYL VANE Sibyl Vane is a character of great importance in The Picture Of Dorian Gray. However‚ she is also a symbol. A symbol of the Dorian Gray of old‚ the way he was before succumbing to a mind numbing world of guilty pleasures and debauchery. Sibyl also represents the beginning of Dorian Grays’ descent into this dark world. A “love” interest of the young Dorian Gray‚ Sibyl represents what Dorian wished to be; young‚ pure‚ and innocent‚ and perhaps naïve of the world
