Purpose: Renewable energy in Indonesia is very abundant, one of which solar energy. With Indonesia's location on the equator, abundant potential can be utilized as an environmentally friendly source electricity. To increase a electricity, it equipped with battery storage system. The most widely used electrical system battery. purpose this study use for DC water pumps. proposed also power, volta...

A jet pump is a type of pump that accelerates the flow of a secondary fluid (driven fluid) by introducing a motive fluid with high velocity into a converging-diverging nozzle. Jet pumps are also known as adductors or ejectors depending on the motivator phase. The ejector's motivator is of a gaseous nature, usually steam or air, while the educator's motivator is a liquid, usually water. Jet pump...

Renewable energy sources are important for reducing carbon emission. There are many ways to integrate renewable energy into existing supply-demand chains. One way is to replace natural gas by biogas. In Meppel, a new urban area is to be equipped with a hybrid energy system with a Combined Heat and Power unit (CHP) at the heart of the system for the production of heat and electricity. The heat i...

To enhance the energy performance of a central air-conditioning system, an effective control method for chilled water system is always essential. However, it real challenge to distribute exact cooling multiple terminal units in different floors via complex network. mitigate hydraulic imbalance many throttle valves and variable-speed pumps are installed, which usually regulated by PID-based cont...

the main purpose of this research was to analyze agricultural water management problems (awmp) in three contexts of: water source, water conveyance and at the farm level, in zarrindasht county, fars province. the research was carried out based on a survey method with a questionnaire compiled for collection of data. questionnaire's reliability was confirmed through a computation of cronbach...

The paper presents and describes a solution for on-line, in-situ automatic cleaning and calibration of stand alone sensors that measure quantities used in the assessment of rivers and lakes water quality. The system, which was also designed to extract water samples for measurement, includes a set of pumps and electro-valves that are controlled by a microcontroller (PIC17C752) based unit. The co...

BACKGROUND VIBATIV is a once-daily, injectable lipoglycopeptide antibiotic approved in the U.S. for the treatment of hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP) caused by susceptible isolates of Staphylococcus aureus when alternative treatments are not suitable. In addition, VIBATIV is approved in the U.S. for the treatment of adult patients with complicated skin...

Abstract Heat pumps can utilize various sources of heat to increase the temperature a room or water. This study uses solar energy as source for high-temperature pumps. The type pump used is vapor compression and produce steam. created model simulation combined with energy. System modeling divided into three subsystems: collector, thermal storage, pump—the WinDali program in simulation. Simulati...

sewerage projects. He was well versed in hydraulics. He could build a dam or reservoir, and lay pipes and sewers. He knew a little bit of plumbing, but was not so sure of his ground in the installation of pumps and engines. He felt equally competent to construct irrigation works, water-works, or land drainage works, because the applications of hydraulics were involved in all these. As regards w...
