backstep: Backstep procedure

In joaobtj/hydirrig: Hydraulic design of irrigation systems

Backstep procedure

Description

backstep Calculate the pressure head and flow rate profile along a lateral line

Usage

backstep(h_fim, d, s, n, dec, coef_em, exp_em, ...)

Arguments

h_fim	Pressure at the end of the line in mca
d	Pipe diameter in milimeters
s	Emitter spacing in meters
n	Number of emitters
dec	Slope on the lateral line
coef_em	Emission coefficient
exp_em	Emission exponent

Examples

backstep(
  h_fim = 10, d = 12, s = 1, n = 5, dec = 0, coef_em = 8.84e-7,
  exp_em = 0.50
)
backstep(
  h_fim = 10
  ,
  d = 12
  ,
  s = c(0.3, 0.3, 1)
  ,
  n = 12
  ,
  dec = 0
  ,
  coef_em = 8.84e-7*3600000
  ,
  exp_em = 0.50
  ,
  q_unit="l/h"
)
