GMAW
Explanation:
It's literally the initials of that type of welding
Answer:
Explanation:
From the question we are told that:
Internally pressurized
Tangential Stress
Axial stress
Generally the equation for maximum normal and shear stresses are experienced by the outer surface is mathematically given by
Therefore
Explanation:
Damkohler numbers are mainly used in chemistry. It is a dimensionless number. It denotes the timescale at which the reaction takes place with relation to the transport phenomenon.
There are two Damkohler numbers
First Damkohler number is the ratio of reaction rate to the convective mass transport rate.
Second Damkohler number is the ratio of reaction rate to the diffusive mass transfer rate
It can be seen from the equations that if the numerator is greater than the denominator then Da>1 and vice versa.
So,
When Da>1, the diffusion rate distribution is lower than the reaction rate.
When Da<1, the reaction rate is lower than the diffusion rate.
