study was undertaken to investigate the characteristics of a Centrifugal pump. The Centrifugal pump is largely used in petrochemical industries to move liquids around the plants and refineries. 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

The Lowest Animal By: Mark Twain. I have been studying the traits and dispositions of the lower animals (so-called)‚ and contrasting them with the traits and dispositions of man. I find the result humiliating to me. For it obliges me to renounce my allegiance to the Darwinian theory of the Ascent of Man from the Lower Animals; since it now seems plain to me that the theory ought to be vacated in favor of a new and truer one‚ this new and truer one to be named the Descent of Man from the

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

Experiment M4 : 2 Stroke‚ 4 Stroke Diesel Engines Abstract Introduction The aim of this experiment was to explore the engines testing methods and to find how the chemical energy in the fuel is converted into power and distributed throughout the system. Six major components of the engine were studied to understand their effect on the engine. Also‚ a multi-cylinder diesel engine is tested for its efficiency. Development of efficiency of the engine has allowed the motor companies to grow very rapidly

Heat pump From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For theoretical background‚ see Heat pump and refrigeration cycle. Outdoor components of a residential air-source heat pump A heat pump is a machine or device that transfers thermal energy from one location‚ called the "source‚" which is at a lower temperature‚ to another location called the "sink" or "heat sink"‚ which is at a higher temperature. Thus‚ heat pumps moves thermal energy opposite to the direction that

Centrifugal pump A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping system.[1][2] Centrifugal pumps are used for large discharge through smaller

Energy is added to the fluid in the form of velocity and pressure as a result of the impeller turning. An engineer must determine the range of flow rates required when using a centrifugal pump.
