Complete Question
Air at 40C flows over a 2 m long flat plate with a free stream velocity of 7m/s. Assume the width of the plate (into the paper) is 0.5 m. If the plate is at a co temperature of 100C,find:
The total heat transfer rate from the plate to the air
Answer:

Explanation:
From the question we are told that:
Air Temperature 
Length 
Velocity 
Width 
Constant temperature 
Generally the equation for Total heat Transfer is mathematically given by

Where
h=Convective heat transfer coefficient

Therefore




Answer:
GMAW
Explanation:
It's literally the initials of that type of welding
Its 0.001
0.01 x100 = 1mm
0.001x100=0.1mm
0.1=10mm
