answer : steady state temperature = 419.713k ≈ 218.7⁰c
Time required to reach a junction ≈ 5 secs
Explanation:
The detailed solution of the given problem is attached below but the solution to the subsequent problem from which the question you asked is referenced to( problem 1 ), is not attached because it was not part of the question you asked
Answer:
Rate of heat transfer to the room air per meter of pipe length equals 521.99 W/m
Explanation:
Since it is given that the radiation losses from the pipe are negligible thus the only mode of heat transfer will be by convection.
We know that heat transfer by convection is given by
where,
h = heat transfer coefficient = 10.45 (free convection in air)
A = Surface Area of the pipe
Applying the given values in the above formula we get
Answer:
Cartesian coordinate system is used to specify any point on a plane.
In two dimensional plane,the two types of axes or coordinates are and
axis.
Explanation:
Cartesian coordinate system specifies each point and every point on axes.
A Cartesian Coordinate system in two dimension also named as rectangular coordinate system.
The two types of axes or coordinates are and
axis.
The horizontal axis is -axis and vertical axis is named as
-axis.
The coordinate system specifies each point as a set of numerical coordinates in a plane which are signed from negative to positive. that is from (,
).
In three dimensional plane, ,
and
coordinates are used and in two dimensional plane,
and
coordinates are used to address any point in the interval (
,
).
For defining both the coordinates, the two perpendicular directed lines - axis and
-axis are drawn.
Now, for example is a point in which indicates that the value of
is
and
is
.
It is drawn by moving units right from the origin to positive
axis and
units upwards from the origin
to positive
-axis.
