Answer:
The answer is below
Explanation:
Both a gage and a manometer are attached to a gas tank to measure its pressure. If the reading on the pressure gage is 65 kPa, determine the distance between the two fluid levels of the manometer if the fluid is a) mercury b) water
Solution:
A manometer is a device used to measure pressure. A manometer is made up of a U shaped tube containing liquid. The difference of pressure in the two arms causes the liquid to reach different heights.
a) The density of mercury () = 13600 kg/m³, Pressure (P) = 65 kPa and g = 9.8 m/s², h = distance between the two fluid levels
b) For water, = 1000 kg/m³, hence:
Answer:227.56 mm
Explanation:
Given data
Elastic modulus= 117 GPa
Diameter=3.6mm
force applied=2460N
Area of cross-section==10.18
and change in length is given by
=
=
L=
L=227.56 mm
Answer:
874 psi
Explanation:
Given a sample mean (x') = 900,
and a standard error (SE) = 10
At 99% confidence, Z(critical) = 2.58
That gives 99% confidence interval as,
x' ± Z(critical) x SE = 900 ± 2.58 x 10
The value of the lower limit is,
900 - 25.8 = 874.2
≈ 874 psi
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.
