what volume of water would be removed from an unconfined gravel aquifer 10,000 m2 in area if the water table in the aquifer drop
Alona [7]

The volume of water is 2500m³ and the fractionof the water is 73.5% of the water contained in that portion of the aquifer would have been removed.

What is aquifer?
An aquifer is a subterranean layer of porous, water-bearing rock, rock fissures, or unconsolidated materials. A water well can be used to obtain groundwater from aquifers. The features of aquifers vary widely. Aquitard is a low-permeability bed along an aquifer, while aquiclude (or aquifuge) is a solid, impermeable region below or covering an aquifer, the pressure of which could form a restricted aquifer.

Area of the unconfined aquifer=10000m².
water table drops by 1m
porosity = 34%
specific yield= 25%
Volume of water removed= Sy× volume
                                          = 0.25×10000×1
                                          = 2500m³

Fraction of water removed = 25/34

                                             = 0.735
                                             = 73.5% of water removed

A car traveling on the highway at 15 m/s accelerates at 3.0 m/s2 for 5.0 s. What is its final velocity?
Nataly_w [17]

Answer:

The answer to your question is:  vf = 30 m/s

Explanation:

Data

vo = 15 m/s

a = 3.0 m/s²

t = 5 s

vf = ?

Formula

vf = vo + at

Substitution

vf = 15 + (3)(5)

vf = 15 + 15

vf = 30 m/s
