// Chemicals savings formulas:
// X - Machine lifetime at your farm - years?
// Y - Yearly costs of chemicals?
// Z - Expected chemical saving with TWIN? (10-30%)

//Cost of chemicals in the period
chemicalsCostFormula: "(X*Y)",
//Result - You save in the total period using TWIN

// Increased spray capacity formulas
// A - Your sprayed area in ha per year?
// B - Sprayer tank capacity in Litres?
// C - Boom width in metres?
// D - Time for filling, mixing and transport in hours?
// E - Amount of water in l/ha - conventional?
// F - Amount of water in l/ha - TWIN?
// G - Driving speed in km/h - conventional?
// H - Driving speed in km/h - TWIN?
