Answer:
(A) Fourier Analysis
Explanation:
Fourier Analysis
It is the form of study of the way a general functions can be represented via the sum of the simple trigonometric functions .
It is named after Joseph Fourier , who represented a function as a sum of its trigonometric functions and it simplifies the study of the heat transfer .
Hence ,
The technique for resolving the complex repetitive waveforms into the sine or the cosine waves and the DC component is known as the Fourier Analysis .
Answer:
True
Explanation:
Wastewater should never be discharged into storm sewers. Storm sewers are constructed to store rainwater.
Rainwater passes through storm sewers to the nearest underground water resource if the wastewater discharge into storm sewers, then they will also pollute the ground water, so usually the dirty water is not put in the storm sewers.
Explanation:
Note: Refer the diagram attached
Apply KVL around 
loop
Answer:
Explanation:
This is the broadened and extended part of the floor and also generally rests on the foundation piles, which are made of seasoned bamboo or wood driven at 0.3 m intervals into the soft soil with the butt end up. The apron serves as protection to scouring and future seepage of water at the gate's sides.
Using
q = k*v,
where q = traffic flow rate, k = density, v = space mean speed.
so, 1800 = k x 40
so, k = 1800/40 = 45 veh/mie on two lanes,
so k = 45/2 = 22.5veh/h/in
