â k = 1 10 f ( k , n ) , {\displaystyle \sum _{k=1}^{10}f(k,n),}. n is a free variable and k is a bound variable; consequently the value of this expression depends on the value of n, but there is nothing called k on which it could depend.
2 Waist - At point specified below HPS (High Point Shoulder) or SNP (Side Neck Point). Measurement taken straight across, edge to edge. 3 Hem - Measured straight or curved along bottom edge, side seam to side seam (whichever is specified on the measurement chart). 4 Shoulder Seam - From HPS/SNP measure along the seam to the outer shoulder edge.
NPSHA is a measure that corresponds to the level of pressure at the pump suction. The higher the pressure, the higher the NPSHA and the better the pump will operate. Normally we measure pressure with a gauge that is calibrated in psig (pound per square inch gauge) or kPa in the metric system.
