A complete mix of an activated sludge system without primary clarification is used for treatment of municipal wastewater with a

flowrate of 12 MGD. The plant components include four clarifiers with a diameter of 80ft and a side-water depth of 14ft. The aeration basin volume is 3 million gallons, the mixed liquor suspended solid concentration of 3,000 mg/L, and the solid's residence time is 5 days. The return activated sludge flow rate is 10 MGD. The effluent suspended solids concentration is negligible. Sludge is wasted from the aeration basin. What is the return of suspended solids concentration (mg/L)

Why would a robot process something faster than a human
pantera1 [17]
A robot is a machine. It is often, or almost always, automatic, which means that it is able to perform activities on its own without the aid of external variables, like humans. It moves in the way that it was originally programmed, or designed to act. These actions are described as 'intents' of its own.

A 4.4 HP electric motor spins a shaft at 2329 rpm. Find: The torque load carried by the shaft is closest to: Select one: a)-27.0
harina [27]

Answer:

Load carried by shaft=9.92 ft-lb

Explanation:

Given:    Power P=4.4  HP

                    P=3281.08 W

<u><em>Power:  </em></u>Rate of change of work with respect to time is called power.

We know that P=Torque\times speed

     \omega=\frac{2\pi N}{60} rad/sec

So that P=\dfrac{2\pi NT}{60}

So   3281.08=\dfrac{2\pi \times 2329\times T}{60}

      T=13.45 N-m         (1 N-m=0.737 ft-lb)

 So T=9.92 ft-lb.

Load carried by shaft=9.92 ft-lb
