Answer:
The surface area of the primary settling tank is 0.0095 m^2.
The effective theoretical detention time is 0.05 s.
Explanation:
The surface area of the tank is calculated by dividing the volumetric flow rate by the overflow rate.
Volumetric flow rate = 0.570 m^3/s
Overflow rate = 60 m/s
Surface area = 0.570 m^3/s ÷ 60 m/s = 0.0095 m^2
Detention time is calculated by dividing the volume of the tank by the its volumetric flow rate
Volume of the tank = surface area × depth = 0.0095 m^2 × 3 m = 0.0285 m^3
Detention time = 0.0285 m^3 ÷ 0.570 m^3/s = 0.05 s
Answer:
----------
Explanation:
Ancient machines have paved the way for improvement by being the foundation for change. these machines made it possible to find flaws so in the next generations, they could fix, develop, and produce better quality machines. eventually this process has reached the present time but after today, the process will continue to produce even better quality machines than the time before. I hope this helps!
Answer:
a)- True
Explanation:
If two statements are inconsistent with each other it means that they are not telling the same, if they are not telling the same it means that only one of them COULD be true, but there is a third option where the two statements are wrong and non statement is telling the true...so:
If we have two statements inconsistent with each other, AT LEAST one of the statements is false.
Usando la ecuación de regresión que modela la frecuencia cardíaca máxima, podemos obtener el valor predicho de los problemas dados así:
La ecuación lineal que modela la frecuencia cardíaca máxima permitida en función de la edad del paciente está relacionada con la fórmula:
<em>x = edad del paciente; m = máx. frecuencia cardíaca permitida</em>
1.) <u>Frecuencia cardíaca máxima permitida para una persona de 50 años:</u>
Sustituye x = 50 en la ecuación:
m = -0,875 (50) + 190
m = 146,25
Por lo tanto, la frecuencia cardíaca máxima permitida es de aproximadamente 146 latidos / min.
2.) <u>Edad para una persona con frecuencia cardíaca máxima de 160 latidos / min</u>:
Sustituye m = 160 en la ecuación:
160 = -0,875x + 190
0,875x = 190 - 160
0,875x = 30
x = 30 / 0,875
x = 34,28
Por tanto, la edad de la persona sería de unos 34 años.
