This is for hydrology. How would I calulate the time it would take for the plume to reach the next well in it's path? Plume is moving in a southeast direction with with the next well at a distance of 61.2m away with a hydraulic gradient of 0.15m between the two wells. Here is the other information I have. Thank You A confined aquifer with the top of the aquifer about 13.5 m below the surface. The aquifer is 5.5 m thick and is bounded by impervious rock below (forming the datum for the hydraulic head measurements) and a clay aquitard above. Analysis of the aquifer material reveals a bulk density of 1.75 g/cm3, porosity of 0.35 and 0.55% organic carbon. After a pumping test, you calculate that the transmissivity of the aquifer is 0.00025 m2/s and the storativity is 0.000055. What monitoring well(s) would you next expect to see toluene found in and in approximately how long?
A confined aquifer with T = 7.0 x 10-3 m2/s and S = 5 x 10-4 is pumped by two wells, 35 m apart. One well is pumped at 7.6 L/s and one at 15.2 L/s. Plot the drawdown h0-h versus distance along a line joining the wells, 4 hours after the start of pumping. Use 5 m increments along the line. How would I go about this question if my initial r1 would equal 0 and and r2 would equal 35m additionally how would I get the pumping rates at each 5 m increments. overall please give a step by step on how I Would go about this question
“For a well draining 80 acres, with thickness 80 ft and permeability 15 md, assume Bo = 1.2, μ = 1.8 cp, rw = 0.3 ft, and the flow is steady-state flow following the Vogel correction. Plot IPRs in one figure for skin va“ues of s = 0, 5, 10, and 20. Assume the reservoir and bubble-point pressure are 5000 psi.”
A capture well is pumping at a rate of 1700 m^3 /day from a confined aquifer with a hydraulic conductivity of 425 m/day, an initial hydraulic gradient of -0.00098 and a saturated thickness of 22 m. Water is flowing from west to east. a. What is the maximum width of the capture zone in m to the nearest ones place? b. What is the distance from the well to the stagnation point in m to the nearest ones place? Consider what sign makes sense. c. True or False: The majority of the capture zone is to the west of the capture well.

Problem 3.5 A well of diameter 0.3 m is constructed to the full depth of an unconfined aquifer of thickness of 150 m. The water table is 10 m below the ground surface. A pumping test of 12 m'/hour has resulted a drawdown of 10 m. Assuming ro = 400 m; calculate the coefficient of permeability of the aquifer. If the flow rate increases to 18 m'/hour, and in the absence of any other data, what will be the best estimate for the drawdown in the well?
A pump test was carried out in an unconfined aquifer of k = 3x10^-6 m/s with a flow rate of 25m3/hour. The radius of the well is 0.5m and the aquifer has a depth of 80m above an impermeable stratum. The drawdown in an observation well at a distance of 150m from the well is 2.5m. Calculate the depth of water in the well and the radius of influence??
QI. s) Q1: A 1 m diameter well penetrates vertically through a confined aquifer (30 m) thick. When the well is pumped at (2712 m³/day), the drawdown in a well 15 m away from pumped well is 1.8 m; while the drawdown in another well 50 m away from pumped well is 0.5 m. Take the maximum head is 40 m. 1- Determine the transmissivity. 2- What is the approximate head in the first well? 3- What is the approximate head in the second well? 4- What is the approximate head in the pumped well for steady-state conditions? 5- What is the approximate drawdown in the pumped well?

Can I get the correct answer for the question.
ENVIRONMENTAL ENGINEERING ( Practice Questions) a). Suppose a well 0.36m in diameter has been pumped at a rate of 3,000cu.m/day for a long enough time that steady-state conditions apply. An observation well located 30m from the pumped well has been drawn down by 1.0m, and another well at 120m is drawn down by 0.4m. The pumped well extends completely through an unconfined aquifer 60.0m thick. GIVEN: For an unconconfined aquifer, Q = πK(h2c1 – h2c2) / [Ln(r1 / r2)] Determine the hydraulic conductivity, K. (7 marks) (ii) Estimate the drawdown at the pumped well. State any assumptions made. b). A confined aquifer 40.0 m thick has two monitoring wells spaced 400m apart along the direction of groundwater flow. The difference in water level in the wells is 4.0m (the difference in piezometric head). The hydraulic conductivity is 40m/day. Estimate the rate of flow per meter of distance perpendicular to the flow. C). Suppose the aquifer, which has a…
