A well pumps at a steady rate of 70gallons/minute (265L/min). It is located 50ft (15.2m) from a lakeshore that is roughly straight. The well is installed in a 6 inch (15.2cm) diameter hole. The well screen and the lake penetrate the same confined aquifer. While pumping, the head in the well is 6.5ft (1.98m) lower than the head in the lake. Estimate the average transmissivity of the aquifer near the well and report your answer inft2/day or m2/day. Assume that without the well pumping, the head at the well is essentially the same as the head in the lake. Be careful to use consistent units in your calculations.
