Answer:
It is because constraints applied automatic by the software (CAD) are supposed to control relationships and geometry between lines, arcs and circles while those manually added are supposed to control the geometry to behave in the manner the user likes the sketch to appear when drawing.
Explanation:
CAD software enables creating sketches using the program by automatic allowing geometric constraints to perform the tasks.Geometry in lines, circles, and other geometric features show collaborating relation that facilitate sketching in the program.For example, two end points appear to make lines remain perpendicular.Other geometric constraints are parallel, and equal.However, the user can manually apply geometric constraints to a sketch to force the geometry in a manner that is suitable to the sketch drawn.That is why a user must manually apply others.
Answer:
h = 23.237 W/m2 K
Explanation:
given data:
flow rate = 1.08*10^6 gm/h = 0.3 kg/s
D = 4.5 cm = 0.045 m
L = 10^4 cm = 100 m
surface temperature = 370 K
Surface heat of vapor = 2190 J/kg.k
From energy conservation principle we have
heat transfer btwn surface and air = heat loss due to flow and temp. drop
where
heat transfer btwn surface and air is due to convection
WHERE
from both above equation we have
putting all value to get heat transefer coefficient
h = 23.237 W/m2 K
So what happens is the host will not kill the y no se que hacer para no one can see it in
Answer:
Assuming steady state condition the temperature distribution is calculated as expressed in the attached solution below
Explanation:
Given data :
thickness : L , inner surface (x) : 0, uniform flux : q"o
fraction : β
volumetric heat generation : q˙(x)=(1−β)q''oα^e−αx
determine the temperature distribution in the quartz
attached below is the detailed solution
Answer:
(a) pulse-amplitude modulation (PAM)
Explanation:
It should be no surprise that pulse amplitude is modulated in <em>pulse-amplitude modulation (PAM)</em>.
