Spray heads in an agricultural spraying system are to be supplied with water through 140 meter of steel pipe from an engine-drive pump. In its efficient operating range, the pump output is 200 m®/hr at a discharge pressure not exceeding 400 kPa (gage). For satisfactory operation, the sprinklers must operate at 200 kPa (gage) or higher pressure. Minor losses and elevation changes may be neglected. Assume that the standard sizes for the pipe are available in 5 mm increments only, i.e. 5 mm, 10 mm, 15 mm and so on. 11. Determine the smallest standard pipe size that can be used. Provide your answer in metres. 12. Determine the resulting pressure drop in Pascals.
