The power of the brick wall it may be how the soiled ness of the wall too keep in the cold
Explanation:
Answer:
0.77978
Explanation:
This is a Poisson distribution problem
Poisson distribution formula is given as
P(X = x) = (e^-λ)(λˣ)/x!
λ = mean = 10 tankers per day
x = variable whose probability is required
The probability that more than 7 tankers arrives in a certain day = 1 - (Probability that 7 or less tankers arrive in a certain day)
P(X > 7) = 1 - P(X ≤ 7)
P(X ≤ x) = Σ (e^-λ)(λˣ)/x! (Summation From 0 to x)
P(X ≤ 7) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + + P(X=6) + P(X=7) + P(X=8)
Computing this,
P(X≤7) = 0.22022
P(X > 7 ) = 1 - P(X≤7) = 1 - 0.22022 = 0.77978
To solve the problem it is necessary to use the concepts related to frictional dissipation per unit mass, energy balance equation and Volumetric flow rate.
The frictional dissipation per unit mass is defined as
Where,
Superficial velocity of fluid
Fluid viscoisty
Porosity
Fluid density
L = Packed bed length
= Effective particle diameter
Through energy balance equation we have that
Neglect the change in velocity and pressure and the work done we have,
We have also that de grade is defined as
With our values and replacing at the previous equation we have,
Previously with the given depth and height we have to
Therefore the Volumetric flow rate,
Therefore the desired volumetric flow rate is 2456gal/min
The answer is osha ensure that employers have right to succeed in what they do best receive information
Answer:
Option D
A mineral’s color reflects the wavelengths of light that are absorbed by the mineral.
Explanation:
Color is one of the physical properties of minerals. Many minerals have a wide range of colors but there are some minerals with one consistent color and such minerals are referred as monochromatic minerals for example azurite. Normally, the streak color tends to be less variable than the color of the whole mineral and impurities or minor chemical components in a mineral react and often control the display color of resultant mineral. Option D is incorrect since mineral's color don't reflect wavelengths of light absorbed by such minerals.
