The quantity heat loss through below-grade basement walls at a depth of 6-7 feet with no insulation is C. 0.069
<h3>What is insulation?</h3>
Insulation is the process of constructing a barrier between two objects that reduces heat transfer by either reflecting thermal radiation or decreasing thermal conduction and convection from one to the other. The insulation will be more or less effective depending on the material of the barrier.
We can directly see the value of heat loss below grade basement walls at different depth from the handbook of fundamentals.
Heat loss through below grade basement walls at depth of 6-7 ft with no insulation is
= 0.069 BTU/hr.ft.0F (In English units)
Hence option ( C ) is correct.

Answer:
output=
Explanation:
output =transfer function ×input
here transfer function G=
input = unit impulse
in S domain unit impulse =1
so output =
=
Answer: C. There is no relationship
Explanation:
At the various temperatures, the flow rates do not seem to show any relation as similar temperatures can yield different flow rates.
The flow rates neither appear to generally increase nor decrease as a result of a decrease or an increase in temperature which means that there is a lack of a positive, negative and curvilinear relationship.
There is simply no relationship.
Answer:
they are used for electrical currents so that they can flow along the appropriate wires in the circuit
Explanation:
Answer:
The value of critical length = 3.46 mm
The value of volume of fraction of fibers = 0.43
Explanation:
Given data
= 800 M pa
D = 0.017 mm
L = 2.3 mm
= 5500 M pa
= 18 M pa
= 13.5 M pa
(a) Critical fiber length is given by
Put all the values in above equation we get
mm
This is the value of critical length.
(b).Since this critical length is greater than fiber length Than the volume fraction of fibers is given by
Put all the values in above formula we get
= 0.43
This is the value of volume of fraction of fibers.
