Engineering is the technical
Answer:
science technology engineering mathematics
Explanation:
Answer:
30 feet
Explanation:
Given data :
design speed = 30 miles/h
super elevation = 0.08
determine the width of the turning roadway
calculate the value of R = V^2 / 15( e + p)
e = 0.08 , p = 0.2 , v = 30
R = (30)^2 / 15 ( 0.08 + 0.2 )
= 900 / 15 ( 0.28 )
≈ 215 ft
pavement width from the calculation above = 28 ft
width of the turning roadway = pavement width + 2 = 30 feet ( because there are two vertical widths joining up the main road at the T junction )
Answer:
It would decrease the SRT
Explanation:
The SRT is the average time it will take for the activated-sludge solids system to decompose. The concept is expressed in days. The retention time is a very important design and operational parameter in the design of an activated sludge digester. The make-up stream from the second clarifier contains a considerable amount of bacteria which are already active. Therefore, the synergistic action of the bacteria makes the sludge to be digested faster. This, In turn, reduces the time it takes to digest the sludge. Thus, the make-up stream lowers the retention time.
Answer:
length of cylinder can not calculated
Explanation:
given data
tensile stress = 10,000 psi
Original length = 1
Original cross-sectional area = 0.1 in²
Yield strength, σy = 9 ksi
Young’s modulus, E = 1000 ksi
solution
we can see that here that applied stress is greater than yield stress of material that is express
1000 ksi > 9 ksi
so here hooks law and strain relation is not working
so length of cylinder can not calculated
as stress applied 10000 psi
