Calculate the rates of seasonal consumptive use and periodic consumptive use during the two irrigation intervals and during the maturation period of a mustard crop of 120 days duration from the following data: (1) Mean soil water contents at sowing and at harvesting in the root zone are 20.5 and 14.5 percent respectively. Mean bulk density of the soil in the root zone is 1.50 g/cm³ Mean soil water contents immediately before and 2 days after the first irrigation of 6cm depth applied at 40 days after sowing are 15.1 and 19.9 percent respectively. (iv) Mean water contents immediately before and after the second irrigation of 6cm depth applied at 75 days after sowing are 14.3 and 19.0 percent respectively. The effective rainfall received by the crop during the first and second irrigation intervals and during the season are respectively 4.3cm, 4.8cm and 13.1cm. (vi) Potential evapotranspiration during the two-day period immediately after the first and second irrigations are 3.0mm and 3.5mm per day respectively. (vii) Rooting depth of the crop is 75cm. (ii) (iii)

After mixing during coagulation or flocculation process followed by 15 min settling, why do we pippete water from the middle of the beaker to measure turbidity.
A stream of 200 lps was diverted from the river and 150 lps were delivered to the field. An area of 3 hectares was irrigated in 8 hours. The root-zone depth was 1.8 m. The run-off averaged 50 lps for 3 hours. The depth of water penetration varied linearly from 1.8 m at a head of the field to 1.2 m at the end of the field. Determine the water-conveyance efficiency, the water-application efficiency, the water storage efficiency, and the water distribution efficiency.

Q2: Wheat is to be grown in a field having a field capacity equal to 27% by weight and the permanent wilting point is 13% by weight. Find the maximum storage capacity in 80 cm depth of the soil (root zone depth), if the apparent specific gravity of the soil is 1.5. If irrigation water must be supplied when the average soil moisture falls to 18%, find the water depth required to be supplied to the field if the water application efficiency is 80%
