The industrial revolution created many jobs, boosted the economy, but created many issues too. Including but not limited too, child labor, decrease in workplace saftey for the sake of profits, hard hours, and many injuries and deaths (i.e. Triangle Shirtwaist Factory Fire). In the short term, companies used the oppertunity of little workers rights to exploit them for profits, yet in the long term boomed the economy and our exports and America's indepence from buying imports.
Answer:
Reynolds number is 293068.43.
Explanation:
Step1
Given:
Water temperature is 98 °F.
Diameter of the pipe is 4 in
Length of the pipe is 870 feet.
Flow rate of water is 260 gallons per minute.
Calculation:
Step2
Water kinematic viscosity at temperature 98 F is ft²/s.
Find the velocity of the water as follows:
Q=AV
V=6.638 ft/s
Step3
Expression for Reynolds number is given as follows:
Here, v is velocity, is kinematic viscosity, d is diameter and Re is Reynolds number.
Substitute the values in the above equation as follows:
Re= 293068.43
Thus, the Reynolds number is 293068.43.
This question is incomplete, the complete question is;
the water depths upstream and downstream of a hydraulic jump is 0.3 m and 1.2 m. Determine flow rate ( in m³ ) if the rectangular channel is 20 m wide.
Answer:
the flow rate is 32.549 m³/sec
Explanation:
Given that
y₁ = 0.3 m
y₂ = 1.2 m
β = 20 m
Now for Rectangular Channel, we know that;
2q²/g = y₁y₂( y₁ + y₂)
where g = 9.81 m/s²
and q = Q/β
so
2(Q/β)²/g = y₁y₂( y₁ + y₂)
we substitute our given values
2(Q/20)²/9.81 = 0.3 × 1.2( 0.3 + 1.2)
2(Q²/400)/9.81 = 0.36(1.5)
2(Q²/400) = 0.54 × 9.81
Q²/400 = 5.2974 / 2
Q²/400 = 2.6587
Q² = 1059.48
Q = √1059.48
Q = 32.549 m³/sec
Therefore the flow rate is 32.549 m³/sec
The two terms are extremely similar and Interconnected. The difference is that cybersecurity often refers to the solution whereas privacy issues are the problem.
