Pressure and flow profile in a subunit

Description

subunit_profile Calculates the pressure and flow profile in a subunit

Usage

subunit_profile(
  h_fim_manifold,
  d_manifold,
  s_manifold,
  s_ini_manifold = s_manifold,
  n_manifold,
  dec_manifold,
  d_lateral,
  s_lateral,
  s_ini_lateral = s_lateral,
  n_lateral,
  dec_lateral,
  coef_em,
  exp_em,
  q_unit = q_unit
)

Arguments

h_fim_manifold	Pressure at the end of the manifold line, mca
d_manifold	Diameter of the manifold line, meter
s_manifold	Spacing between lateral lines in the manifold line, meter
s_ini_manifold	Spacing of the initial section of the manifold line, meter
n_manifold	Number of lateral lines in the manifold line
dec_manifold	Slope of the manifold line, decimal
d_lateral	Diameter of the lateral line, milimeter
s_lateral	Spacing between emitters on the lateral line, meter
s_ini_lateral	Spacing of the initial stretch of the lateral line, meter
n_lateral	Number of issuers on the lateral line
dec_lateral	Lateral line slope, decimal
coef_em	Coefficient of the flow-pressure equation of the emitter
exp_em	Exponent of the flow-pressure equation of the emitter
