Problem $2$:

A $1\mathrm{.}25-$ft diameter well penetrating fully in a confined aquifer is pumped at a rate of $0\mathrm{.}035$ cfs $.$ The hydraulic conductivity of the aquifer is $77$ ft$/$day$.$ The elevation of the top of the aquifer is $322$ ft and that of the bottom of the aquifer is $314$ ft $.$ The drawdown at an observation well $350$ ft from the main well is $1\mathrm{.}45$ ft $,$ what is the drawdown at the well? Also, find the time it takes for the flow from observation well to reach the pumping well, the porosity of the aquifer is $0\mathrm{.}35.[10]$ Hint: Make sure that for the calculation of travel time the equation related to travel time with a well in aquifer is used.
