lateral_head_diameter: Pressure and diameter on the lateral line

In joaobtj/hydirrig: Hydraulic design of irrigation systems

Pressure and diameter on the lateral line

Description

lateral_head_diameter calculates lateral line diameter and pressure for a given average flow rate and a given flow rate variation

Usage

lateral_head_diameter(
  q_req_lateral,
  q_var_lateral = 10,
  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
q_var_lateral	Lateral maximum variation in flow rate, percentage
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

Examples

args_lateral_head_diameter <- list(
  q_req_lateral = 5.5555e-7*3600000
  ,
  q_var_lateral = 10
  ,
   s_lateral = 0.20
   ,
    s_ini_lateral = 1
    ,

  n_lateral = 12
  ,
   dec_lateral = -0.00
   ,
    coef_em = 1.67e-7*3600000
    ,
     exp_em = 0.52
     ,
     q_unit="l/h"
)
do.call(lateral_head_diameter, args_lateral_head_diameter)
