Question

Calculate the spacing of trocars for a field according to the following: Irrigation water gives love once every ten days - The ground water surface rose above the water level in the drainage before irrigation (0.3 m). The permeability of the soil to water is 1 m/ day and the porosity of drainage is 0.05 - The level surface of the main deck is 1.8m - The maximum height of the groundwater level is 1m from the surface of the earth - the diameter of the field trenches pipes is 20cm, a value of a value. de = 4.49 when L = 80 m the value of de = 4.72 when L = 90 m They are located at a greater depth 9.8m than the earth's surface​
