Answer:
162.4
Explanation:
Because yea thats the answer no need to tell you why ok bye
Explanation:
A.
P = Ds * g * h
Height, h = 5053 ft
In m,
1541.165 m
g = 9.81 m/s^2
SG = density of substance, Ds/density of water
1.03 = Ds/1000
= 1030 kg/m^3
P = 1030 * 9.81 * 1541.165
= 1.56 x 10^7 N/m^2
1 Psi = 6894.76 Pa = 6894
76 N/m^2
= 2258.6 psig.
B.
Pressure = 4400 psig
Since,
1 Psi = 6894.76 Pa = 6894
76 N/m^2
= 3.03 x 10^7 Pa
Density = 3.03 x 10^7/(1541.165 * 9 81)
= 2006.6 kg/m^3
SG = density of substance, Ds/density of water
= 2006.6/1000
= 2.01.
C.
Density of barite = 4.370 * 1000
= 4370 kg/m^3
Total mass of slurry = mass of barite + mass of seawater
= 1030 + 4370
= 5400 kg in 1 m3 of slurry.
Mass fraction = mass of barite/total mass of slurry
= 4370/5400
= 0.81.
D.
The mud weight is a key factor. Too low mud weight may result in collapse problems, hence spill of the well will not be contained. This is because of the pressure of escaping oil against a column of fluid (the mud) having a density significantly higher than those of seawater and oil.
Answer : Gain of electrons.
Explanation : In a oxidation-reduction reaction often called as redox reactions, during the process of reduction the electrons are gained by the reduced species in the chemical reaction, whereas in the oxidation process the electrons are lost by the oxidised species. The total transfer of electrons forms the base of the redox reactions.
Redox chemical reactions are those where the oxidation states of atoms are changed.
Answer:
False
Explanation:
Metals are materials that exist in the form of solid (state of matter). It is not true that solid solutions are only formed with metals. A solid solution is a <u>solid-state solution of one or more solutes in a solvent. </u>The solid solution can be formed with different forms. In general, solid solutions <u>formed by mixing a foreign elements Y (solute) with a perfect crystalline element X (solvent) </u>and atoms of both X and Y share the various crystal sites.
<u>Answer:</u> The amount of energy absorbed by water is 5390 Calories
<u>Explanation:</u>
To calculate the amount of heat absorbed at normal boiling point, we use the equation:
![q=m\times L_{vap}](https://tex.z-dn.net/?f=q%3Dm%5Ctimes%20L_%7Bvap%7D)
where,
q = amount of heat absorbed = ?
m = mass of water = 10 grams
= latent heat of vaporization = 539 Cal/g
Putting values in above equation, we get:
![q=10g\times 539Cal/g=5390Cal](https://tex.z-dn.net/?f=q%3D10g%5Ctimes%20539Cal%2Fg%3D5390Cal)
Hence, the amount of energy absorbed by water is 5390 Calories
