NPSH, NPSHr & NPSHa Definition NPSH is an acronym that stands for Net Positive Suction Head. NPSH is a measure of the absolute pressure present in a liquid. There are two ways of expressing NPSH relative to a centrifugal pumping system: NPSHa: The Net Positive Suction Head Available at the pump impeller inlet.

A to Z List of Neurological Disorders NPH occurs if the normal flow of CSF throughout the brain and the spinal cord is blocked in some way, causing the ventricles to enlarge, putting pressure on the brain.NPH can occur in people of any age, but it is most common in the elderly population.n these cases, the cause of the disorder is unknown. Symptoms of NPH include progressive mental impairment and dementia, problems with walking, and impaired bladder control, leading to urinary frequency and/or incontinence.

Net Positive Suction Head definition â NPSH for pumps Net Positive Suction Head definition – NPSH for pumps. Net Positive Suction Head or NPSH for pumps can be defined as the difference between liquid pressure at pump suction and liquid vapor pressure, expressed in terms of height of liquid column. Suction head is the term used to describe liquid pressure at pump suction in terms of height of liquid column. When vapour pressure is also expressed in terms of equivalent height of liquid column, and subtracted from the suction head, the difference is npsh available at the pump suction.

Normal Pressure Hydrocephalus (NPH) Normal pressure hydrocephalus occurs when excess cerebrospinal fluid accumulates in the brain's ventricles, which are hollow fluid-filled chambers. NPH is called normal pressure because despite the excess fluid, cerebrospinal fluid pressure as measured during a spinal tap is often normal.As brain ventricles enlarge with the excess cerebrospinal fluid, they can disrupt and damage nearby brain tissue, causing symptoms of NPH.ecause the symptoms of NPH may overlap with those of Alzheimer's and other dementias, experts recommend that a person with suspected NPH undergo examination by a neurologist with extensive experience evaluating brain disorders that affect movement, thinking skills and physical functions.

Is there any confusion about NPSH? Is there any confusion about NPSH? Net Positive Suction Head (NPSH) is perhaps the most misunderstood concept in pumping technology. The main source of confusion stems from multiple uses of the term in different but related contexts. One usage of the term NPSH is to denote the suction performance characteristic of the pump itself, independent of the system into which it is installed.
