The time drawdown data listed below for a confined aquifer was measured at an observation well located 300 ft away from a well pumped at 1500 gpm. Determine T and S for the aquifer using the Cooper-Jacob method of solution. For the T and S values that you obtained, after how many minutes of pumping is the Cooper-Jacob approximation valid

dont think so

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
