Spectral DNC is used to prevent hair loss and restore hair growth. This topical hair loss product is produced by DS Laboratories. Spectral DNC's active ingredients include Minoxidil and Aminexil.

a System curve is used in hydrolic anylyses to dtermine the duty point of a pump for a certain pipe line.

The pump curve and system curve are plotted on the same graph and where the two cross each other is the duty point, the curve is a Head(meters) vs Flow(m3/hour).

The system curve

Head = static head + head loss due to friction in pipe + secondary head loss

*This is calculated for a certain flow to determine the Head so it can be plotted on the curve
