Answer:
6.5 × 10¹⁵/ cm³
Explanation:
Thinking process:
The relation 
With the expression Ef - Ei = 0.36 × 1.6 × 10⁻¹⁹
and ni = 1.5 × 10¹⁰ 
Temperature, T = 300 K
K = 1.38 × 10⁻²³
This generates N₀ = 1.654 × 10¹⁶ per cube
Now, there are 10¹⁶ per cubic centimeter
Hence,

Answer:
In the acid processes, deoxidation can take place in the furnaces, leaving a reasonable time for the inclusions to rise into the sla*g and so be removed before casting. Whereas in the basic furnaces, deoxidation is rarely carried out in the presence of the sla*g, otherwise phosphorus would return to the metal.
 
        
             
        
        
        
Answer:
a) 5.2 kPa 
b) 49.3%
Explanation:
Given data:
Thermal efficiency ( л ) = 56.9% = 0.569 
minimum pressure ( P1 ) = 100 kpa
<u>a) Determine the pressure at inlet to expansion process</u>
P2 = ?
r = 1.4 
efficiency = 1 - [ 1 / (rp) ]
 ] 
    0.569   = 1 - [ 1 / (rp)^0.4/1.4 
1 - 0.569  = 1 / (rp)^0.285 
∴ (rp)^0.285 = 0.431 
rp = 0.0522 
note : rp = P2 / P1 
therefore P2 = rp * P1 = 0.0522 * 100 kpa
                                    = 5.2 kPa  
b) Thermal efficiency 
 Л = 1 - [ 1 / ( 10.9 )^0.285 ] 
    = 0.493 = 49.3% 
 
        
             
        
        
        
Answer:
