Find the drawdowns at a distance 3 m from the production well after one hour of pumping and at a distance of 350 m after one day of pumping.
- Q1 What can we say about the ratio of specific potential and specific kinetic energy of a subcritical open channel flow?In Figure, when the pressure heads at A and B are 3.05 m and 89.9 m, respectively, the pump AB adds 75 kW to the system shown. What elevation can be maintained at reservoir D?A tube well of 15 cm diameter penetrates fully an artesian aquifer 27 m thick. Determine the permeability of the aquifer if a steady discharge of 30 lps is obtained from the well under a drawdown of 3.0 m at the well face.Take radius of influence equal to 200m.
- In Figure below, with 35 L/s of seawater (sp gr 1.03) flowing from 1 to 2, the pressure at 1 is 100 kPa, and at 2 is -15 kPa. Point 2 is 6 m higher than point 1. Compute the lost energy in kPa between 1 and 2.A confined aquifer has a thickness of 85 ft. An 86-in diameter well drilled to the bottom of the aquifer, as shown in fig 3-10, if the hydraulic conductivity of the aquifer is 10 ft / day, and if water is originally 170 ft deep in the well, calculate approximately the maximum rate of flow that can be pumped from the well without dewatering any part of the aquifer. Assume 1000 ft reasonable value for the radius of influence. What will be the average velocity ( Darcy velocity ) of flow in the aquifer at a distance 20 ft from the center of the well?The rectangular channel shown in the following figure has a width of 10 ft and transports water at 19,229 ft3/min. If the elevation of the channel bed drops by 0.75 ft, determine the specific energy (in ft) after the depression. Provide your answer with two decimals. Note: The solution method is the same as for a rise except the Δh term will be negative to account for the depression.
