Two discharge wells (1 and 2) penetrating an unconfined aquifer are pumped at constant rates of 3,000 and 500 m^3 per day , respectively. The steady-state head (i.e., water table height) measured at an observation well is 40 meters . The observation well is 50 meters from well 1 and 64 meters from well 2. The water table height measured at a second observation well is 32.9 meters , which is located 20 meters from well 1 and 23 meters from well 2. Determine the aquifer permeability K (in m/day).

Expert Solution

ANSWER:-

PERMEABILITY:- Property of a material that lets fluids (such as water or water vapor) to diffuse through it to another medium without being chemically or physically affected. Opposite of permeance.

it is denoted by 'k'.

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...

Two liquid streams are flowing at constant rates into a blender. One is benzene, which flows at a measured rate of 20.0L/min, and the other is toluene. The blended mixture enters a storage tank (inner diameter = 5.5m) equipped with a sight gauge. During an interval in which no liquid leaves the storage tank, the liquid level in the tank is observed to increase by 0.15 meters over a one-hour period. Calculate the flow rate of toluene into the blender...
