Hydraulic efficiency of the centrifugal pump is mainly depends on mass flow rate, Head and RPM. Finding the best combination with the above said parameters and the best geometry of the pump is possible by using three dimensional CFD simulations.For designers, prediction of operating characteristics curve is most important. All theoretical methods for prediction of efficiency merely give a value; but one is unable to determine the root cause for the poor performance. Due to the development of CFD code, one can get the efficiency value as well as observe actual behavior and the root cause for poor performance by using CFD Analysis of equipment. Author considered 8/6 AH pump for the three dimensional fluid flow analysis and validated the pump hydraulic efficiency with the experiment results. It is observed the behavior of the hydraulic efficiency with respect to the pump performance characteristics. Centrifugal pumps should be run at best efficiency point. Generally the radial force developed on the shaft will be high, if operates away from the BEP and it may leads to shaft damage. So it is important to find out best efficiency point.

The ability of controlling a flow field to obtain a desired change is of great importance. In this work I have studied air flow control through an aircraft's inlet device. To observe the effect of creating an auxiliary inlet in the side of the inlet device I’ve studied first an one-dimensional compressible flow through a pipe with variable section and with an auxiliary inlet. By varying the position of the auxiliary inlet I’ve analyzed the effect of suction/injection of fluid through this inlet upon the flow through the pipe. Further on I’ve studied the air flow through the inlet device of a supersonic aircraft at take-off conditions. In these conditions along the inlet device occur considerable total pressure losses. To reduce these losses I've created an auxiliary inlet in the side of the inlet device through which to take place an outside air injection. The purpose was to find a relationship between the medium total pressure at the compressor's entry and the opening of the auxiliary inlet knowing that at the the compressor's entrance the Mach number of the air flow must be 0.5.
This research effort emphasizes on cooking of turmeric rhizomes by using solar steam generation system. This study will help to farmers, scientists, industrialists and new entrepreneurs engaged in growing and processing of turmeric. The Scheffler cooker is modified for cooking of turmeric. The performance of solar steam cooker was evaluated for two conditions viz. no load condition and full load condition with turmeric. Tests were carried out to know the trend of various operating parameters such as inlet and out let temperature of receiver, inlet and out temperature of receiver, solar insolation, wind velocity and pressure of steam.
This Filter Pump is a high effective way to purify water via its built-in filtration system. There are two separate hoses to be connected to a swimming pool: one pumps water via a pool outlet; the other sends filtered water into a pool inlet. Besides, it can send 2500gal of water through it every hour. With this high-performance Filter Pump, a steady flow of clean and clear water will tank up your swimming pool. Features Sending 2500gal (9463L) of water through it every hour. Great for sanitizing pool water by pumping it through a cartridge filter and returning the filtered water to a swimming pool. An environmentally friendly way to keep a steady flow of clean, clear water in your pool. Be connected to a pool using two separate hoses. One hose pumps water via a pool outlet; the other hose sends filtered water into a pool inlet. Ideal for 1100-57500L swimming pool.
