Efficiency analysis take by laboratorium and financial analysis using NPV and BCR are done in order to obtained dicharge and pressure from each pump. At the end of the research, one out of 5 home water pump brands will be selected as the optimal working home water pump with low operational...
They suggested the condensation and evaporation of a working fluid within a piston cylinder to produce suction and delivery of water through the pump respectively. The results of their theoretical simulation indicated a pump efficiency of 9% when operated with a temperature difference of 60 °C ...
A total of 54 experimental trials were conducted to study the effects of four factors on the efficiency of scale removal with multiple flat-fan nozzles at an orientation of 25°. The factors investigated are (1) number of nozzles; (2) spray injection pressure; (3) stand-off distance ...

Both tools were considered effective in recognising and predicting hazards and could improve the level of security, deter mishaps to machinery and operators and, also, to improve the efficiency and consistency of the model by reducing operational issues. Whether a model is labelled as critical in ...

√The parts where water flows including pump casing ,pump cap and impeller are made of resin bonded sand aluminum mould, ensuring smooth and streamline flow channel and appearance an d enhancing the pump's efficiency. √The direct connection between motor and pump simplifies intermediate d...
The seasonal performance of a heat pump indicates its average performance during the heating and/or cooling season, taking into account the different energy demands and their variability over time. Several European and international regulations and policies related with energy efficiency and the reduction...
It can be said that water sensitive intervention is a strategic tool to achieve the vision of a “water sensitive city.” Ref.13defined “water sensitive intervention” as a means of enhancing water use efficiency and diversifying water sources through water sensitive city principles. Water sensitiv...
