Calculation of Predictable of Water Quality on the Ocean Area by Joseph-Sendner equation and Nitta equation

 1 Distance from emission source：r (m) 0＜r＜r1 2 Angle of diffusion：θ (°) - 3 Concentration of polluted matters at r1(m)：S1 (ppm) At outer edge of diffusion area 4 Concentration of polluted matters of drainage water：S0 (ppm) Emission source 5 Drainage volume：Q (m^3/day) - 6 Thickness of diffusion layer：d (m) See below Remarks 7 Diffusion speed：P (cm/sec) =1.0±0.5(cm/sec) 8 Graph x：Q(m^3/day),y：S(ppm) x：r(m),y：S(ppm) x：θ(°),y：S(ppm) x：d(m),y：S(ppm) x：P(cm/sec),y：S(ppm) Plot Input Data： YesNo 9 Number of gridlines of Graph x-axis, y-axis Figure： OnOff

Remarks

・If "Q" is under 5*10^4(m^3/day), input d(m) should be under 1(m) and if over 10*10^4(m^3/day),should be 1.5～2.0(m).
・Concentration of polluted matters at r(m)：S
・Distance from emission source：r
・Angle of diffusion：θ
・Concentration of polluted matters at r1(m)：S1
・Concentration of polluted matters of drainage water：S0
・Drainage volume：Q
・Thickness of diffusion layer：d
・Diffusion speed：P
