Concept explainers

Groundwater Flow

The term groundwater refers to the water which is found beneath the earth's surface. Pores present in the soil and rocks with fractures make a passage for rainwater to enter the earth's surface and deposit as groundwater. The flow nature and direction of groundwater under the earth's surface directly impacts the strength and compressibility of the soil, which reflects its ability to support structural loads.

Question

The oil derrick has drilled 5 km into the ground before it strikes a
crude oil reservoir. When this happens, the pressure at the well
head A becomes 25 MPa. Drilling "mud" is to be placed into the
entire length of pipe to displace the oil and balance this pressure.
Assume all pressures are gage pressures (Figure 1)

Environmental Enginee... During a recuperative test, the water is pumped out 2.8 m initially and allowed to recuperate. It was observed that the water level rises by 1.45m in 80 minutes. If the diameter of the well is 3.45m, determine by what amount the diameter need to be increased to get a yield of 5 litre per sec under a depression head of 1.65m.
