A cylindrical specimen the some metal alloy having actually an elastic modulus of 124 GPa and also an initial cross-sectional diameter of 4.2

sdrta.net:

the maximum size of the specimen before deformation is 0.4366 m

Explanation:

Given the data in the question;

Elastic modulus E = 124 GPa = 124 × 10⁹ Nm⁻²

cross-sectional diameter D = 4.2 mm = 4.2 × 10⁻³ m

tensile pack F = 1810 N

maximum allowable elongation Δl = 0.46 mm = 0.46 × 10⁻³ m

Now to calculate the maximum size

*
for the deformation, we usage the complying with relation;

*
= < Δl × E × π × D² > / 4F

so we substitute ours values into the formula

*
= < (0.46 × 10⁻³) × (124 × 10⁹) × π × (4.2 × 10⁻³)² > / ( 4 × 1810 )

*
= 3161.025289 / 7240

*
= 0.4366 m

Therefore, the maximum size of the specimen before deformation is 0.4366 m

sdrta.net:a) recovery element = 53.3% ,bi) volume the oil per acre-ft = 11090.64bbl/acre-ft

bii) bulk volume the the reservoir in acre-ft = 1000 acre-ft

c) 62214.74 cubic feet

Explanation: a) recovery element is the portion amount the oil that have the right to recovered native a reservoir, the is the oil developed divided by oil originally in location

Recovery factor= 1 - (Soi/1-Swi)

= 1 - (0.35/1-0.25)

= 0.533 × 100%

= 53.3%

bi) volume of oil which might be recovered every acre-ft = 7758.porosity.(1- Swi-Soi)

= 7758 x 0.2 x (1-0.25-0.35)

= 620.64 bbl/acre-ft

bii) mass volume that the reservoir in acre-ft= Area x thickness

= 100 acres x 10 ft

= 1000 acre-ft

c) complete volume of oil in cubic feet

since us have acquired volume together 1000 acre-ft we simply multiply it by the volume of oil gained in sdrta.net bi)

= 1000 acre-ft x 620.64 bbl/ acre-ft

= 620640bbl

So we convert from barrel(bbl) to cubic feet, and 1 barrel is equal to 5.609 cubic feet, therefore to transform the sdrta.net from barrel to cubic feet we multiply the sdrta.net 620640 bbl through 5.609
