Answer:
Sprockets.
Explanation:
A chain drive is an efficient technique used for the transmission of mechanical power from one point to another. For example, it is used for transmitting power to the wheels of a bicycle, motorcycle, motor vehicle and other machineries such as chain saw etc.
Chain drive ratio is the ratio between the rotational speeds of the input and output sprockets of a roller chain drive system. This ultimately implies that, chain drive ratio is the ratio of the number of teeth on the driving sprocket (T1) divided to the number of teeth on the driven sprocket (T2).
Also, the chain drive ratio can be calculated by dividing the number of teeth on the large sprocket by the number of teeth on the small sprocket.
Additionally, the rotational speed of a sprocket is measured in revolutions per minute (RPM).
One of the issues with the roller chain is that, as the roller chain moves round the sprocket link by link, it affects its speed (surge) due to the change in acceleration and deceleration i.e the rise and fall of its pitch line.
Answer:
Given Data:
concentration of sewer Csewer = 1.2 g/L
converting into mg/L = Csewer = 1.2 g/L x 1000 mg/g = 1200 mg/L
flow rate of sewer Qsewer = 2000 L/min
concentration of sewer Cstream = 20 mg/L
flow rate of sewer Qstream = 2m3/s
converting Q into L/min = 2m3/s x 1000 x 60 = 120000 L/min

I don’t even know lol i’m just tryna bring my points up sorry.
Answer:


Explanation:
given data:
Diameter =





from continuity equation



![v_2 = [\frac{d_1}{d_2}]^2 v_1](https://tex.z-dn.net/?f=v_2%20%3D%20%5B%5Cfrac%7Bd_1%7D%7Bd_2%7D%5D%5E2%20v_1)
![= [\frac{0.200}{0.158}]^2 \times 100](https://tex.z-dn.net/?f=%3D%20%5B%5Cfrac%7B0.200%7D%7B0.158%7D%5D%5E2%20%5Ctimes%20100)

by energy flow equation

and q =0, w =0 for nozzle
therefore we have


but we know dh = Cp dt
hence our equation become
