Performance Evaluation of El Batts Pumping Station
El Batts Pumping station is located in Fayoum Governorate on the right bank of existing Batts drain about 120 km south of Cairo, at entrance of 0.6 km north-west of Tamiya village. It is equipped with four vertical mixed flow pumping units. The main objectives of this pumping station are to increase the cultivated area by 10000 feddan in the north of Bahr Wahby, improve the irrigation for 20000...
متن کاملWater Hammer with Column Separation:
Column separation refers to the breaking of liquid columns in fully filled pipelines. This may occur in a water hammer event when the pressure drops to the vapor pressure at specific locations such as closed ends, high points or knees (changes in pipe slope). A vapor cavity, driven by the inertia of the parting liquid columns, will start to grow. The cavity acts as a vacuum, a low-pressure poin...
متن کاملMultiple Scales Analysis of Water Hammer Attenuation
A multiple scales analysis is used to construct a uniformly accurate approximation to water hammer pressure wave attenuation that is initiated by a sudden valve opening. The method of analysis is well suited to the study of a water hammer that possesses several time scales and is applied to a mild generalization of the classical equations. It should prove useful for finding attenuation curves w...
متن کاملInvestigation of Hydraulic Problems in Pumping Station; Case Study
Pumping stations play an important role in agriculture development projects. Performance of the pumping stations should satisfy water requirements, and management. There are many problems face these pumping stations affecting their reliability and stability. Hydraulic problems are the most important item in the field of pumping station operation and design. Motivation of this research was prese...
متن کاملSolar Water Pumping System
PV array is increasingly employed for water pumping system. In this paper, the developed boost converter steps up the voltage produced by the PV array to a value which is suitable to run a single-phase induction motor. The inverter converts DC to AC is controlled by using sinusoidal pulse width modulation (SPWM) technique. By using a LCfilter the harmonics are eliminated and pure sine wave is o...
