A 0.75-m radius well fully penetrates a 24-m thick unconfined aquifer and is pumped at a rate of 10 L/s (or 864 m3 /day). The drawdown in an observation well 30 m from the pumped 3 well is 1.6 m after a long period of pumping. The drawdown in another observation well 60 m from the pumped well is 1.1 m after the long period of pumping. Determine a) the hydraulic conductivity of the aquifer, b) the expected drawdown in the pumped well, and c) the radius of influence (i. e., when there is no drawdown so the head is 24 m) of the pumped well

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
