Issues During Construction

Construction is the combination of art, science, and engineering to build buildings, bridges, structures, roadways, highways. airports, etc. The construction business is a challenging and promising business worldwide with certain risk factors involved. Increasing demand for mankind leads to the growth of several construction companies which specialize in different construction projects. These construction companies initiate their construction process under certain agreements and time durations called the construction contract.

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

A pump can lift water at a discharge of 0.15 m³/s to a head of 25 m. The critical cavitation number (o) for the pump is found to be 0.144. The pump is to be installed at a location where the barometric pressure is 9.8 m of water and the vapour pressure of water is 0.30 m of water. The intake pipe friction loss is 0.40 m. Using the minimum value of NPSH (Net Positive Suction Head), the maximum allowable elevation above the sump water surface at which the pump can be located is

There are two identical groundwater pump facilities that is operating 6 kilometers apart. The hydraulic conductivity is 40m/day. Each pump well structure has a tube diameter of 75cm. The original water table has an elevation of 110 m. However, it is maintained that the maximum drawdown (at the tube) is 18m. The water table will not change at the midpoint between the two pump wells. Determine the drawdown at a point 2 km from the pump.
