The following values for a confined aquifer are measured from the ground surface: depth to piezometric level before pumping = 25 ft depth to top of aquifer = 75 ft depth to bottom of aquifer = 125 ft. A 24-inch diameter well is driven to the bottom of the aquifer an pumped at 500 gpm until steady state conditions are attained. The drawdown at an observation well 50 ft from the pumping well is 10 ft and the drawdown at...

Let us assume that the water table on the island is 2 m above sea level. Then, t 2 m, so 2 m/0.03-h 66.67 m. Thus we can predict that if we drill a hole on the island we would not come to salty groundwater for approximately 67+ 2 meters, or about 69 m from the top of the water table. This would be 67 m below sea level. a] Suppose you found a place on the island where...

The hydraulic head loss in a pipe may be determined by the Darcy-Weisbach Equation as follows: H=(f*L*V^2)/(2*D*g) Where L is the length of the pipe, V is the follow velocity of water in a pipe, D is the pipe diameter, f is the coefficient of friction and g is the gravitational acceleration (32.2 ft/sec^2) Suppose the length of the pipe L has a constant length of 10 ft and the pipe has a constant diameter of .5 ft. The coefficient...

Water is pumped from a well to a water tower (an above-ground reservoir) through a 330 ft long galvanized iron pipe (ε-0.0005 ft) with a 2-in diameter. The water surface in the well is 10 ft below the ground and the water surface in the tower is 60 ft above the ground. The water is to be delivered at a rate of at least 370 L/min. The sum of the minor loss coefficients is 2.1 a) Using the pump performance...
