Answer:
True
Explanation:
This is true. Welding fumes are a combination of metallic oxides, silicates and also fluorides. the formation of these films are a result of a metal being exposed to heat above its boiling point and a condensation of its vapours into good fine particles. such films are made up of particles from the material that one is welding and also particles from electrode.
Answer:
A)
B)
Explanation:
Given data:
P-1 = 100 lbf/in^2
degree f
effeciency = 80%
from steady flow enerfy equation
where h1 and h2 are inlet and exit enthalpy
for P1 = 100 lbf/in^2 and T1 = 500 degree F
for P1 = 40 lbf/in^2
exit enthalapy h_2
from above equation
[1 Btu/lbm = 25037 ft^2/s^2]
b) amount of entropy
