flowrat {AgroTech}

Calculation of required spray nozzle flow

Description

This is a function to determine the required flow rate of a spray nozzle

Usage

flowrat(Q, q, V, W = 50)

Arguments

Q

Application rate (L/ha)

q

Nozzle flow (L/min)

V

Sprayer speed (km/h)

W

Spacing between spray nozzles (cm)

Details

Application rate (L/ha):

Q=\frac{60000*q}{V*W}

Nozzle flow (L/min):

q=\frac{Q*(V*W)}{60000}

Sprayer speed (km/h):

V=\frac{\frac{60000*q}{Q}}{W}

Spacing between spray nozzles (m):

W=\frac{\frac{60000*q}{Q}}{V}

Value

Returns values for flow, application rate, sprayer speed, spacing between spray tips

Note

60000 Units conversion factor
