Two piezometers are installed 2430 m apart in a confined aquifer. The head at the first piezometer is measured as 29.1 m and the head at the second piezometer as 26.7 m. The aquifer has a saturated thickness of 17.3 m, and hydraulic conductivity of 8x10-4 m/s, and effective porosity of 0.16.

Determine:

1.1. without any calculation, predict the direction of groundwater flow

1.2. the discharge rate through the aquifer in m3/d/m of aquifer width

1.3. the specific discharges (Darcy velocity)

1.4. the pore velocity (seepage velocity)

1.5. the time for water to travel between two piezometers in years

A field test is conducted in a confined aquifer by pumping a constant discharge of 14.9 m3/hr from 20-cm-diameter well. After an approximate steady state is reached, a drawdown of 0.98 m is measured in the pumped well. Also measured are drawdowns of 0.73 m, 0.65 m, 0.60 m, and0.57 m, respectively, at 8.0 m, 30.0 m, 80.0 m, and 132 m from the pumped well. Determine the transmissivity of this aquifer. Also, determine how far away from the well...

In a pumping test of a confined aquifer, the steady state water level in an observation well 10m from the pumping well was 38mOD and was 42 mOD in another observation well 100m from the pumping well. The water levels in both wells were steady at 50mOD before the test began and then water was pumped at a constant rate of 0.005m^3/s from the pumping well. Estimate the aquifer transmissivity. If the aquifer is 15m thick, estimate the hydraulic conductivity...

Two loudspeakers are located 2.53 m apart on an outdoor stage. A listener is 21.4 m from one and 22.2 m from the other. During the sound check, a signal generator drives the two speakers in phase with the same amplitude and frequency. The transmitted frequency is swept through the audible range (20 Hz to 20 kHz). (a) What is the lowest frequency fmin,1 that gives minimum signal (destructive interference) at the listener's location? By what number must fmin,1 be...

Two loudspeakers 6.0 m apart are playing the same frequency. If you stand 10.0 m in front of the plane of the speakers, centered between them, you hear a sound of maximum intensity. As you walk parallel to the plane of the speakers, staying 10.0 m in front of them, you first hear a minimum of sound intensity when you are directly in front of one of the speakers. PART A What is the frequency of the sound? Assume a...
