Answer:
8.5 days
Explanation:
Given data :
Flow ( Q ) = 2.6 MGD = 11819.834 m^3/day
BOD = 131 mg/L
BOD loading rate = 35 Ibs/1000 ft^3 per day = 0.5606 kg/m^3/day
<u>Calculate the sludge age of the facility </u>
Given the BOD applied to the aeration tank = 11819.834 m^3/day * 131mg/l
= 1548.398 kg/day
first calculate the volume of the aeration tank
V = BOD applied / BOD loading rate
V = 1548.398 / 0.5606 = 2762.03 m^3
Hydraulic Detention time = V / Q
= 2762.03 / 11819.834 = 0.2336 day = 5.6 hour
next : determine the mass rate of the waste
= 44% * 0.5606 kg/m^3/day
= 0.2466 kg/m^2/day
finally determine the sludge age
= V * Xt / ∅w * R
= ( 2762.03 m^3 * 2100 * 10^-3 ) / ( 0.2466 * 2762.03 kg/day )
= 8.5 days
Answer: information security managers
Explanation:
Information security managers is an individual in charge of making sure that company's or organization's equipments such as computers, network, data etc are protected against security breach, computer viruses, hackers, etc. The person also keep assets in confidentiality, integrity, and makes them available when needed. Failure to do this might lead to the loss of confidential data, security breach, cyber crimes, etc which will cause a serious set back in a company's operations especially in the information and technology department, it might also lead to fine sanctions from regulatory body for the failure to protect data, it will also lead to financial loss,etc.
Answer:
Essentials. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
Answer:
The answer of this question is 19.89142857
Yes.
electric current refers to directional negative-to-positive electrons from one atom to the next. Liquid conductors and gas conductors, electric current refers to electrons and protons flow in the opposite direction.
