$($c$)$ Two wells, A and B$,$ diameters $250mm$ and $300mm$ respectively, are pumped at $250\frac{m^3}{h}r$ and $150\frac{m^3}{h}r$ within a confined aquifer. If the thickness of the aquifer is $25m,$ the coefficient of hydraulic conductivity is $35\frac{m}{?}$ day and the radius of influence for well A is $150m$ and that for well B is $75m,$ working from first

principles verify whether pumping at well A has an influence on the drawdown in well B$,$ if well B is at a distance of $250m$ from well A$.$
