Question

5) A pumping test was conducted in a confined aquifer using a constant pump discharge of 6.00 m³/hr. The drawdowns measured at an observation well located 20.0 m from the pumped well are in the following table. Determine the aquifer transmissivity, the storage coefficient, and the drawdown after 50 hours.

Time(hr)	0.05	01.0	0.20	0.50	1.0	2.0	5.0	10.0	20.0
S at 20m well	0.52	0.66	0.79	0.98	1.11	1.25	1.43	1.57	1.71
