Answer:
Stress-concentration
In the machine component the stress become concentrate at the point a particular point and due to this crack formation takes places and after some time some the machine component become fails.High stress concentration means high stress at that point.
It is very important in the design point of view because we have to find out where stress concentration is high and needs to take proper factor of safety to avoid the failure of the machine component.Generally at sharp corner,sudden change and complex shapes stress concentration is high.
The total evaporation loss of water is 87.873 ×
lbm /day.
<u>Explanation:</u>
Assume A is the water and B is air.
A is diffusing to non diffusing B.
By the table 6.2 - 1 at 25°C, the diffusivity of air and water system is 
.
Total pressure P = 1 atm = 101.325 KPa
= 23.76 mm Hg
= 
= 0.03126 atm
= 3.167 K Pa
When air surrounded is dry air, then 
= 0 mm Hg
R = 8.314 
= 
= 101.325 - 3.167
= 98.158 K Pa
= 101.325 - 0
= 101.325 K Pa
= 99.733 K Pa
Z = 1 ft = 0.3048 m
T = 298 K
= 
= 0.11077 × 
mol/ 
.s
= 0.11077 × × 18 × (60×60×24)
= 0.1723 
/ .day
Area of individual pipe is
A = 0.00051
= 0.1723 × 0.00051
= 0.000087873 lbm/day
In 1000 ft length of ditch,there will be a 10 pipes. The amount of evaporation water is
= 10 × 0.000087873 = 0.00087873 lbm /day
The total evaporation loss of water is 87.873 × lbm /day.
Answer: 150m
Explanation:
The following can be depicted from the question:
Dimensions of outer walls = 9.7m × 14.7m.
Thickness of the wall = 0.30 m
Therefore, the plinth area of the building will be:
= (9.7 + 0.30/2 + 0.30/2) × (14.7 × 0.30/2 + 0.30/2)
= 10 × 15
= 150m
Answer:
This is False because people can have more than 1
