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)

2) The switch in the circuit below has been closed a long time. At t=0, it is opened.
saul85 [17]

Answer:

  il(t) = e^(-100t)

Explanation:

The current from the source when the switch is closed is the current through an equivalent load of 15 + 50║50 = 15+25 = 40 ohms. That is, it is 80/40 = 2 amperes. That current is split evenly between the two parallel 50-ohm resistors, so the initial inductor current is 2/2 = 1 ampere.

The time constant is L/R = 0.20/20 = 0.01 seconds. Then the decaying current is described by ...

  il(t) = e^(-t/.01)

  il(t) = e^(-100t) . . . amperes

"A communication between two devices is over the maximum limit of an ethernet frame size. The Transmission Control Protocol (TCP
Sliva [168]

COmmunication Devices

Explanation:

  • TCP/IP, or the Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP can also be used as a communications protocol in a private network (an intranet or an extranet).

  • The sequence number in a header is used to keep track of which segment out of many this particular segment might be. The next field, the acknowledgment number, is a lot like the sequence number. The acknowledgment number is the number of the next expected segment.

  • The 32 bit sequence number field defines the number assigned to the first byte of data contained in this segment. TCP is a stream transport protocol. To ensure connectivity, each byte to be transmitted is numbered.
