pump characteristic than net positive suction head (NPSH).Many pump installations are plagued by cavitation problems.With centrifugal pumps,excessive cavitation causes a reduction in head and efficiency,but less cavitation can cause i...

Net Positive Suction Head (NPSH) in centrifugal and positive displacement pumps For example, if you know the flow rate your application requires, you find the gallons per minute (or hour) rate along the bottom horizontal line of the curve and then draw a line up to the head/PSI you requir...
First, by looking at the net positive suction head required (NPSHr) curve of the pump. This is a calculation of how much absolute pressure is needed at the inlet to keep the system from cavitating. Second, calculate the NPSH available (NPSHa). This value represents the absolute...
What they refuse to face is species, including man had to find its that there is a limit to what can be done in this way, "niches" in this world of competition for Lebensraum and whereas there is no limit to the increase of geometrical resources. Sadly, however, each species was ...

Place dependence, in contrast, concerns the potential of a particular setting to satisfy the needs and goals of an individual and involves an assessment of how well this setting compares with others in satisfying these needs. This comparison involves both the emotional bonds to and the activities ...
