Answer:
d
Explanation:
is the because that's the amount of work in making machine can do producing heat
Answer:
r = 1.922 mm
Explanation:
We are given;
Yield stress; σ = 250 MPa = 250 N/mm²
Force; F = 29 KN = 29000 N
Now, formula for yield stress is;
σ = F/A
A = F/σ
Where A is area = πr²
Thus;
r² = 2900/250π
r² = 3.6924
r = √3.6924
r = 1.922 mm
Answer:
Pyrolysis
It is a biomass in anaerobic conditions results in the production of solid charcoal, liquid bio-oil and fuel gases. . Pyroolysis can be categorized into three groups depending on environment conditions, namely conventional pyrolysis, fast pyrolysis and flash pyrolysis.
