lateral_head: Pressure required on the lateral line

In joaobtj/hydirrig: Hydraulic design of irrigation systems

Pressure required on the lateral line

Description

lateral_head Calculates the pressure at the beginning of the lateral line for a given average flow rate

Usage

lateral_head(
  q_req_lateral,
  d_lateral,
  s_lateral,
  s_ini_lateral = s_lateral,
  n_lateral,
  dec_lateral,
  coef_em,
  exp_em,
  q_unit = q_unit
)

Arguments

q_req_lateral	Average flow required on the lateral line, m3/s
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
q_unit=q_unit	additional parameters

Examples

args_lateral_head <- list(
  q_req_lateral = 5.5555e-7*3600000
  ,
   d_lateral = 12
   ,
    s_lateral = 0.20
    ,
     s_ini_lateral = 1
     ,

  n_lateral = 200
  ,
   dec_lateral = -0.00
   ,
    coef_em = 1.67e-7*3600000
    ,
     exp_em = 0.52
     ,
      q_unit="l/h"
)
do.call(lateral_head, args_lateral_head)
