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:
attached below
Explanation:
Cylindrical steel rod : diameter ( D ) , length L, uniform temperature T
Initial temp of water : To, heat transfer coefficient between steel rod surface and water : h1
<u>The energy balance equation can be written as :</u>
Rate of convectional heat loss = Rate of decrease in internal energy with respect to time
cp = heat capacity of body, v = volume , р = density of body
attached below is the heat transfer differential equation and boundary and initial conditions
Answer:
-Computer going blank
.
-Mouse pointer freezing.
-Keyboard getting stuck.
Explanation:
Any problems with the computer related to its hardware will consist of issues directly related to the physical components of the PC or computer. So any problem involving the physical component of the computer, then it can be termed as a hardware problem.
Based on the problems given in the option, the hardware issues will be problems with the computer, mouse, and keyboard. These form the physical parts of the computer so they will be a hardware issue.
Thus, the <u>correct answers are the third, fourth, and fifth options</u>.
