1 2	subunihd(DLL, K, x, DLD, SeLL, SeLD, nLL, ne, dec, qreq, imax = 100, toler = 1e-06, qvr)

`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
`qvr`	Emitter flow variation

D diameter lateral line, pressure head at the end, iter number of iterations, tempo time
