Answer:
I believe the correct answer would be Weight.
Weight is a force that gravity exerts on an object.
Hope this helped :))))
The separation and purification process is used for DEVELOPING VACCINES. The development of vaccines must follow strict guidelines.
A vaccine is a biological preparation used to protect against harmful diseases (e.g., viruses) in a simple and safe manner.
Vaccine purification is a strict process consisting of clarification, concentration and chromatography in order to separate the extract that contains the active principle of the vaccine.
The techniques used for vaccine filtration include membrane filtration, depth filtration and centrifugation.

The factor of Safety by Maximum Distortion Energy Theory is given as: N = 6.04
<h3>
What is Maximum Distortion Energy Theory?</h3>
According to this idea, failure by yielding happens when the distortion energy per unit volume in a condition of combined stress equals that associated with yielding in a basic tension test at any location in the body.
<h3>
What is the calculation for the above value?</h3>
Note that we are given the following:
A solid Steel bar subjected to a bending force of F = 55kN
Torsional load T = 30 kN-mm; and
Yield Strength (sy) = 280Mpa
Sut = 330 Mpa
The formula for Normal Stress is given as:
= [UP/πd²] + [ (32* f * L)/πd³]
= [(4 * 8 * 10³)/π * (0.02)²] + [(32 * 55 *10³ * 0.1)/ π * (0.02)³]
= 25.46 + 7.003
= 32.5 Mpa
Tyz = (16T)/πd³
= (16 * 30)/ π * (0.02)³
= 19.098
Tyz = 19.098
Following from the above, sate of stress, we have:
α₁ = αₓ = 32.46 Mpa; and
α₂ = Tyz = 19.098 Mpa;
α₃ = -Tyz = -p19.098 Mpa;
Utilizing the formula given by the Maximum Distortion Energy Theory:
α₁² + α₂² + α₃² - (α₁α₂ + α₂α₃ + α₃α₁)
= Sy²/N²
→ 32.46² + 19.098² + 19.098² - ( 32.46* 19.098 - 19.098² -32.46 * 19.098)
= 280/N²
N = 6.04

Answer:
To* = 1074.9k ( stagnation temperature )
Po* = 0.467 MPa ( stagnation pressure )
Explanation:
Given data:
Po1 = 1.6 MPa
To = 430°c + 273 = 703 k
Mach number at inlet ( M1 )= 3
Mach number at exit ( M2 ) = 1
at M1 = 3
To1 / To* = 0.65398 ( value gotten from Rayleigh's flow gas tables )
therefore To* = 1074.9k
also
Po1 / Po* = 3.42445 ( value gotten from Rayleigh's flow gas tables )
therefore Po* = 0.467 MPa
at M2 = 1
To2 = To* = 1074.9k
Po2 = Po* = 0.467 MPa
using both Rayleigh's flow table and Isentropic Tables the values of stagnation temperature and stagnation pressure are the same at the exit
