Head loss explanation

The most likely explanation for this head loss of 7 ft is frictional loss in the suction line. This reduces the available NPSH from 46 to 39 ft. But this is still a lot more available NPSH than the 14 ft of required NPSH needed to pump 110 GPM. 

It should be mentioned that a recent publication (H ) showed that the pitch (frequency) of sound induced by microwave pulses of widths less than 50 ps persisted as the subject s head was lowered into saline water, while the loudness diminished roughly in proportion to the depth of immersion. Upon complete immersion, auditory sensation disappeared. For pulse widths longer than 50 ps, even partial immersion resulted in loss of perception. This was interpreted as being at odds with the thermoelastic theory. There is, however, an explanation that does seem to fit the data. 

P-RARE) promoter. In established breast cancer cell lines the relationship between RARP basal levels and sensitivity to retinoic acid is not simple classical studies have demonstrated a loss of RARP in a number of breast cancer cell lines [22], and these authors state that in the majority of cases the ER" cell lines expressed the receptor, while most of the ER" cells failed to do so. However, other studies failed to show significant levels of the same receptor in several ER cell lines [32]. A possible explanation may come from the existence of mutated RARP forms in ER" cells, that may or not be recognized, depending on the detection methods used. These observations need to be further evaluated, and confronted with other cellular systems, e.g. head and neck cancer cell lines, where an inverse relationship has already been demonstrated between RARP levels and differentiation markers.
