The minimum radius of the curve to the vehicle to provide safe travel is 2339.2 ft
<u>Explanation:</u>
Given -
Speed allowed, v = 70mph
1 mph = 1.467 fps (feet per second)
Therefore, v = 70 X 1.467 fps
Superelevation, e = 0.05 inches/inch
Coefficient of side friction, fs = 0.09
Minimum radius of the curve, r = ?
We know,
r = v² / g ( fs + e/100 )
where,
g = acceleration due to gravity in feet
g = 32.2 lb.ft / lbf.s²
r = ( 70 X 1.467 )² / 32.2 ( 0.09 + 0.05 )
r = 2339.2 ft
Therefore, the minimum radius of the curve to the vehicle to provide safe travel is 2339.2 ft
<u>Explanation:</u>
At temperature is and relative humidity is 86% therefore, the humidity ratio is 0.0223 and the specific volume is 14.289
At temperature is and Relative humidity is 40% therefore, the humidity ratio is 0.0066 and the specific volume is 13.535.
To calculate the mass of air can be calculated as follows:
Now , we going to calculate the volume,
The time which is required to fill the cistern can be calculated as follows:
Now, putting the value in above formula we get,
Therefore, the hours required to fill the cistern is 4.65 hours.
Answer:
c. V2 equals V1
Explanation:
We can answer this question by using the continuity equation, which states that:
(1)
where
A1 is the cross-sectional area in the first section of the pipe
A2 is the cross-sectional area in the second section of the pipe
v1 is the velocity of the fluid in the first section of the pipe
v2 is the velocity of the fluid in the second section of the pipe
In this problem, we are told that the pipe has a uniform cross sectional area, so:
A1 = A2
As a consequence, according to eq.(1), this means that
v1 = v2
so, the velocity of the fluid in the pipe does not change.
