Answer:
The waste flow rate is 81.05 m3/h
Explanation:
According to the given data we have the following:
Influent SS concentration (CIn): 220 mg/L
Influent flow rate (QIn) : 450 m3/h
Effluent concentration (Cout): 45 mg/L
Waste sludge concentration (Cw): 10,000 mg/L
Qout + Qw= 450 m3/h
CIn QIn=Cout Qout+ Cw Qw
220*450=45Qout + 1000Qw
45Qout+1000Qw=99,000
Therefore, Qout=398.95 m3/h
Qw=81.05 m3/h
The waste flow rate is 81.05 m3/h
Answer: "Altered''
Explanation:
A mental process which forms or produces amental process which produces a lack of connection in a person's thoughts, memories, feelings, actions, or sense of identity. lack of connection in a individual's minds,feelings, or sense of identity is known as the Dissociative Identity Disorder(DID).
It can be treated with talk therapy. The disorder is divided into three namely; Dissociative identity disorder.
Dissociative amnesia and
Depersonalization disorder.
"Individuals with dissociative identity disorder have learned to cope with extremely stressful life circumstances by creating ALTERED personalities that unconsciously control their thinking and behavior when they are experiencing stress."
Answer:
The increase in pressure of the gas is found to be 15.92 KPa
Explanation:
The additional pressure is equivalent to the pressure exerted by the weight of the mass increased over the area of piston:
Increase in Pressure = ΔP = Weight/Area
ΔP = mg/πr²
m = mass = 25 kg
g = 9.8 m/s²
r = radius of cylinder = 7 cm = 0.07 m
ΔP = (25 kg)(9.8 m/s²)/π(0.07 m)²
ΔP = 245 N/0.01539 m²
<u>ΔP = 15.92 KPa</u>
Therefore, the increase in pressure of gas is 15.92 KPa.
Answer:
V₂=43.58 m/s
Explanation:
Given that
P₂=200 KPa
T₂=90°C
V₂=? m/s ( exit speed)
T₁=30°C
P₁=100 KPa
V₁=350 m/s
We know that
Heat capacity for air Cp=1.005 KJ/kg.k
We know that for air change in enthalpy only depends only on temperature
Now from first law for open system
V₂=43.58 m/s
Answer:
D. Leak-proof
Explanation:
Used oils are required to be stored in closed containers or tanks which will remain closed when oil is not added or removed. Alternatively, used oils can be stored in containers labeled "Used Oil" for regulated hazardous waste storing. A leak-proof container is one that has no drips and dribbles when the container lid is closed. These containers should be kept in good conditions away from rusting, leaks or deteriorations. It is important to mention that used oil should not be stored in anything apart from tanks and leak-proof storage containers.
