`DLL`	Diameter lateral line in meters
`K`	Emission coefficient
`x`	Emission exponent
`DLD`	Diameter manifold in meters
`SeLL`	Emitter spacing in meters
`SeLD`	Lateral line spacing in meters
`nLL`	Number of lateral lines in meters
`ne`	Number of emitters in meters
`dec`	Slope on the lateral line
`qreq`	Flow rate required at the emitters in cubic meters per second
`imax`	Maximum number of iteration
`toler`	Maximum tolerance
`HfimLDa`	Maximum pressure head at the end of the manifold in meters
`HfimLDb`	Minimum pressure head at the end of the manifold in meters

HfimLD pressure head at the end of the manifold, qsistema system flow rate, iter number iterations, tempo time
