Answer: False
Explanation: Welding process is the joining process of two metals in which they are melted using the heat and then cooling it down and fuse them.Base metal is the melted and then some filler substance is added in the metal and then kept for the fusion process so that joining can be done. Therefore like fusion welding includes the process of melting work piece , so the statement in the question is false.

Answer:
V₂=43.58 m/s
Explanation:
Given that
P₂=200 KPa
T₂=90°C
V₂=? m/s ( exit speed)
T₁=30°C
P₁=100 KPa
V₁=350 m/s
We know that
Heat capacity for air Cp=1.005 KJ/kg.k
We know that for air change in enthalpy only depends only on temperature
Now from first law for open system
V₂=43.58 m/s
