How to calculate herbicide rates and calibrate herbicide applicators Uniformly applying chemicals at proper rates is essential for effective pest control. A slight variation in the application rate with some chemicals may result in poor control of the pest or injury to the crop or environment, causing lost time, effort and money.
Jul 14, 2020 The surface area is 100 x 50 5,000 square feet. There are 9 square feet in a square yard, so the project area in square yards is 5,0009 about 556 square yards. Confirm the thickness of the asphalt to be placed. For our example, say 3 inches of asphalt thickness is required. Determine the density of the paving material.
Aug 07, 2017 How to Calculate the Spread Rate in Asphalt Paving. Correctly calculating the amount of material that is required to complete the project is essential to a successful asphalt paving assignment.

Spray Nozzle Flow Rate Calculator This calculator is meant to assist you with estimating the flow rate of a spray nozzle at pressures that arent listed in a catalog or if you do not have a catalog readily available Many nozzle companies use a part number that describes the spray angle and flow rate
The Calculation. Lets say you sprayed 5L of water and it covered exactly 25 x 20 metres. Thats 500 square metres, which is 5 of a hectare, or a 20th of a hectare. If the published rate per hectare is 2L of chemical, then the rate per 5L of water according to that personal calibration trial would be one 20th of 2L, which is 100ml.
