Accoding to The ASHRAE Handbook - Fundamentals 2005 Chapter 39 Table 3. The U value of Steel is 26.2 or an R value of .0382. Steel has little or no resistance to heat transfer.
Shear modulus or Rigidity modulus:For material subjected to shear, Within the elastic limit, the shear stress is proportional to the shear strain.The value of Modulus of rigidity for steel is 80 - 100KN/mm^2
please i will said what i do but please make acheck if u have asteel pipe and want to know the weight of it you have to know the following 1- the outer diameter 2- the thickness of the pipe the u do the following ] (outer diam - thickness) * 3.14 * 7.85 * thikness * lenght of pipe (in millemeter) / 1000000 = the weight of the pipe * Note that : all dimension are in millimeter
computer engineers nekede dpunkman was here before u
The friction between the train and the railway tracks!
inshallah r u stupid or something. a steel ruler has a much higher melting point due to the giant lattice of electrostatic bonds, with very high heat energy need to the break them. on the other hand, the plastic ruler only contains weak intermolecular bonds, and thus little heat energy is needed. Ik ur all grown up now. i wish you luck with your life kind regards, Thine Mother
There isNO such thing as satinless steel u spac.
The U value is the inverse of the R value. For R value 19 insulation the U value is 1/19, or 0.0526.
a wall hanger. $130. Depending on shape. Are u willing to sell?
You dont but u need iron
To convert U vals To R Vals 1/u = r val
u have to steel it or buy it
If you mean: 5u+10 = u+46 Then the value of u is 9
copper would have a higher U value
galvanised steel is a lot more safer....... if u go by the book.... it is upto 10 times stronger than stainless steel in aluminum
I asked u
steel plate (found underground) or get a metal coat after u get national dex go to the house in iron island and the 6 gym leader will give u it
to make a steel bar u need 1 iron ore and 2 coal ores
