Answer: False
Explanation: Reynolds number is the number for determining he flow pattern of the behavior of fluids.It judges the flow of the fluid ans states whether it is of turbulent or laminar natured. This number has the property of kinematics as well as statics. It can also be defined as the ratio between the inertial force to viscous force.It's length changes along with change length of the horizontal plate .Thus, the statement given is false.
Answer:
(a) ![318.471lbs/inch^2](https://tex.z-dn.net/?f=318.471lbs%2Finch%5E2)
(b) ![2.196mega\ pascal](https://tex.z-dn.net/?f=2.196mega%5C%20pascal)
Explanation:
We have given load = 1000 lbs
And diameter of the rope d = 2 inches
So radius ![r=\frac{d}{2}=\frac{2}{2}=1inch](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bd%7D%7B2%7D%3D%5Cfrac%7B2%7D%7B2%7D%3D1inch)
Area ![a=\pi r^2=3.14\times 1^2=3.14inch^2](https://tex.z-dn.net/?f=a%3D%5Cpi%20r%5E2%3D3.14%5Ctimes%201%5E2%3D3.14inch%5E2)
(a) Tension ![T=\frac{load}{area }=\frac{1000}{3.14}=318.471lbs/inch^2](https://tex.z-dn.net/?f=T%3D%5Cfrac%7Bload%7D%7Barea%20%7D%3D%5Cfrac%7B1000%7D%7B3.14%7D%3D318.471lbs%2Finch%5E2)
(b) We know that 1 lbs = 4.4482 Newton
So 1000 lbs = 1000×4.4482 = 4448.8 N
And ![1inch^2=0.000645m^2](https://tex.z-dn.net/?f=1inch%5E2%3D0.000645m%5E2)
So 3.14
= 3.14×0.000645 =![2.0253\times 10^{-3}m^2](https://tex.z-dn.net/?f=2.0253%5Ctimes%2010%5E%7B-3%7Dm%5E2)
So
=![2.196mega\ pascal](https://tex.z-dn.net/?f=2.196mega%5C%20pascal)
Answer:
A) Level D ( before development )
B) Level E ( After development )
Explanation:
A) Calculate the level of service before the development
First we calculate the base free flow speed ( BFFS )
= posted speed limit + 5 mi/hr.
= 50 + 5 = 55mi/hr.
Next determine free flow speed ( FFS )
= BFFS - ![f_{lw} - f_{lc} - f_{m} - f_{A}](https://tex.z-dn.net/?f=f_%7Blw%7D%20-%20f_%7Blc%7D%20%20-%20f_%7Bm%7D%20%20-%20f_%7BA%7D)
= 55 - 6.6 - 0.65 - 0 - 2.25 = 45 mi/hr.
The remaining part of the solution is attached below
The level of service = D
given that:
Vp = 1537.096 pc/hr/In
Density = 34.157 pc/mi/In
FFS = 45 mi/hr
B ) Calculate the level of service after the development
attached below is the detailed solution
The level of service = E
given that
Vp = 1816.568 pc/hr/In
Density = 40.368 pc/mi/In
FFS = 45 mi/hr

Check the explanation
Explanation:
The transferred energy calculations can be done using the equation:
This is when:
• power is calculated in watts (W)
• energy is calculated in joules (J)
• time is calculated in seconds (s)
it can also be calculated by utilizing the same equation but with different units:
• when energy is measured in kilowatt-hours (kWh)
• when power is measured in kilowatts (kW)
• and when time is measured in hours (h)

Answer:
B.29
Explanation:
In general purpose acme thread:
Nominal depth of thread=0.5![ltimes Pitch](https://tex.z-dn.net/?f=ltimes%20Pitch)
Included angle =29 degrees
Generally Acme thread are following types
1.General purpose(G) Acme
2.Centralizing(C) Acme
3. Stub Acme
Centralizing(C) Acme threads have tighter tolerance during manufacturing as compare to General purpose(G) Acme threads.
