The purpose of having a ventilation system on board a motorized vessel is : To remove flammable gas from a vessel to avoid explosions.
<h3>Meaning of ventilation system</h3>
A ventilation system can be defined as a system that allows for removal of gases from a vessel to the atmosphere.
A Ventilation system is very important in every motorized vessel because they help to eliminate or remove flammable gases that are dangerous and are liable to explode when held in a large amount in the engine.
In conclusion, The purpose of having a ventilation system on board a motorized vessel is to remove flammable gas from a vessel their by avoiding explosions.

Answer:
a) 
, b) 
Explanation:
The Brinell hardness can be determined by using this expression:
Where 
and 
are the indenter diameter and the indentation diameter, respectively.
a) The Brinell hardness is:
![HB = \frac{2\cdot (1000\,kgf)}{\pi\cdot (10\,mm)^{2}} \cdot \left[\frac{1}{1-\sqrt{1-\frac{(2.50\,mm)^{2}}{(10\,mm)^{2}} } } \right]](https://tex.z-dn.net/?f=HB%20%3D%20%5Cfrac%7B2%5Ccdot%20%281000%5C%2Ckgf%29%7D%7B%5Cpi%5Ccdot%20%2810%5C%2Cmm%29%5E%7B2%7D%7D%20%5Ccdot%20%5Cleft%5B%5Cfrac%7B1%7D%7B1-%5Csqrt%7B1-%5Cfrac%7B%282.50%5C%2Cmm%29%5E%7B2%7D%7D%7B%2810%5C%2Cmm%29%5E%7B2%7D%7D%20%7D%20%7D%20%20%5Cright%5D)
b) The diameter of the indentation is obtained by clearing the corresponding variable in the Brinell formula:
![d = (10\,mm)\cdot\sqrt{1-\left[1-\frac{2\cdot (500\,kgf)}{\pi\cdot (300)\cdot (10\,mm)^{2}} \right]^{2}}](https://tex.z-dn.net/?f=d%20%3D%20%2810%5C%2Cmm%29%5Ccdot%5Csqrt%7B1-%5Cleft%5B1-%5Cfrac%7B2%5Ccdot%20%28500%5C%2Ckgf%29%7D%7B%5Cpi%5Ccdot%20%28300%29%5Ccdot%20%2810%5C%2Cmm%29%5E%7B2%7D%7D%20%20%5Cright%5D%5E%7B2%7D%7D)
