FEASIBILITY STUDY OF THE COST OF TRANSPORTING WASTEWATER FOR IRRIGATION PURPOSES IN THE ADMINISTRATIVE DISTRICT OF KARBALA, IRAQ

Introduction.The study presents an assessment of the economic feasibility of different pipe materials used to transport treated wastewater.The choice was made between pipes made of ductile iron, glass-fiber reinforced polyester (GRP), concrete, and plastic.Hydraulic calculations of operation of an irrigation water supply and distribution system wer

The major needs in machining are high material removal rate, good work surface finish and low tool wear.These objectives can be achieved by reducing tool wear using proper cutting fluid during machining.The effect of some cutting fluids namely: Mentholated spirit, paraffin, and soluble oil on Heart Rate Board the flank wear of High-speed steel and
