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:
atomic radius R = 0.157 nm
metal atomic weight = 72.27 g/mol
Explanation:
given data
parameters a = 0.413 nm
parameters b = 0.665 nm
parameters c = 0.876 nm
atomic packing factor = 0.536
density = 3.99 g/cm³
to find out
atomic radius and atomic weight
solution
we apply here atomic packing factor (x) that is
atomic packing factor (x) = ..................1
put here value we get
atomic packing factor =
R =
R =
atomic radius R = 0.157 nm
and
now we get here metal atomic weight that is
metal atomic weight = ....................2
metal atomic weight =
metal atomic weight = 72.27 g/mol
