Your friend has two substances A and B which are compressed liquid and superheated vapor respectively. Both are in rigid vessels
1 answer:
Answer:
Following are the solution to the given question:
Explanation:
The material is necessary to cook since frying is a speedy process for evaporation.
Drug A is now in the compressed fluid area, and the material would not boil if the pressure is chilled. Because the ship is solid, its substance A claim is false.
Unless the volume comprises of a drop in the heat, the B substance reaches a vapor pressure area and a wet region. That's the area that melting may occur. His claim for material B could therefore be true.

Answer:
a) 0.01558 Ω per 1000 feet
b) 0.0923 Ω per mile
c) 3.57%
Explanation:
<u>a) Calculate and verify the DC resistance </u>
Dc resistance = R = р
for aluminum at 20°C
р = 17 Ωcmil/ft
hence R = 17 * 1000 / ( 113000 ) = 0.01527 Ω per 1000 feet
there when there is an increase in resistance of 2% spiraling
R = 1.02 * 0.01527 = 0.01558 Ω per 1000 feet
<u>b) Calculate the DC resistance at 50°C </u>
R2 = R1 ( )
where ; R1 = 0.01558 , T = 228 , t2 = 50, t1 = 20 ( input values into equation above )
hence R2 = ( 0.01746 / 0.189 ) Ω per mile = 0.0923 Ω per mile
<u>c ) Determine the percentage increase due to skin effect </u>
AC resistance = 0.0956 ohm per mile
Hence; Increase in skin effect
= ( 0.0956 -0.0923 ) / 0.0923
= 0.0357 ≈ 3.57%
Given:
Outer Diameter, OD = 90 mm
thickness, t = 0.1656 mm
Poisson's ratio, = 0.334
Strength = 320 MPa
Pressure, P =3.5 MPa
Formula Used:
1). =
2). factor of safety, m =
Explanation:
Now, for Inner Diameter of cylinder, ID = OD - 2t
ID = 90 - 2(1.65) = 86.7 mm
Outer radius, = 45mm
Inner radius, = 43.35 mm
Now by using the given formula (1)
=
=
=93.74 MPa
Now, Using formula (2)
factor of safety, m = \frac{320}{93.74} = 3.414
