develop new sources of drinking water to supply a total water demand of 70 m3s Three water sources are available Each has different costs associated With pumping and transmission Not enough high quality water is available from one source to supply the city So the city Will have to blend the water sources together to meet the requirement that the hardness level should not exceed 145 gm3 How much water should be pumped from each source to meet the hardness standard at the lowest cost Lsyuurmll Emma Saum 1 lelti water auailae I IIEI 51 41 mgf Ha rd near 253131 E F39E Hill I 45 air13
