Answer:
time = 224 days
Explanation:
given data
thick = 30 m
piezometers = 280 m
head between two = 1.4 m
aquifer hydraulic conductivity = 50 m
porosity = 20%
solution
we get here average pole velocity that is get by using Darcy law that is
Va = 
................1
here Va is average pole velocity and k is hydraulic conductivity and 
is porosity
here v is = 
...........2
v = 50 × 
v = 0.25 m/day
and here average linear velocity Va will be
Va = 
Va = 
Va = 1.25 m/day
travel time for water will be
time = 
time = 224 days
Answer:
61257.6 kW per day
Explanation:
The rating of the refrigerator is given as : 709 w
This means the power consumption is 709 joules per second
The operating time is given as 10 hours.
Change hours to second as
1 hour = 3600 seconds
10 hours = 36000 seconds
Apply the rating as;
709 w = 1 s
? = 36000 seconds
perform cross product to get;
709 * 36000= 25524000 w
25524000 = 25524kW
For a day, 24 hours will be;
25524 kW = 10 hours
? =24 hours
={24*25524}/10 = 61257.6 kW per day
Answer:
∆S1 = 0.5166kJ/K
∆S2 = 0.51826kJ/K

Check attachment for solution
Answer:
The average velocity is 0.203 m/s
Explanation:
Given;
initial displacement, x₁ = 20 yards = 18.288 m
final displacement, x₂ = ¹/₃ x 18.288 = 6.096 m
change in time between 5:02 PM and 5:03 PM, Δt = 3 mins - 2 mins = 1 min = 60 s
The average velocity is given by;
V = change in displacement / change in time
V = (x₂ - x₁) / Δt
V = (18.288 - 6.096) / 60
V = 0.203 m/s
Therefore, the average velocity is 0.203 m/s
