Answer:
18 kJ
Explanation:
Given:
Initial volume of air = 0.05 m³
Initial pressure = 60 kPa
Final volume = 0.2 m³
Final pressure = 180 kPa
Now, 
the Work done by air will be calculated as:
Work Done = Average pressure × Change in volume
thus, 
Average pressure =  = 120 kPa
  = 120 kPa
and, 
Change in volume = Final volume - Initial Volume = 0.2 - 0.05 = 0.15 m³
Therefore, 
the work done = 120 × 0.15 = 18 kJ
 
        
             
        
        
        
Answer: The exit temperature of the gas in deg C is  .
.
Explanation:
The given data is as follows.
 = 1000 J/kg K,   R = 500 J/kg K = 0.5 kJ/kg K (as 1 kJ = 1000 J)
 = 1000 J/kg K,   R = 500 J/kg K = 0.5 kJ/kg K (as 1 kJ = 1000 J)
 = 100 kPa,
 = 100 kPa,     

We know that for an ideal gas the mass flow rate will be calculated as follows.
      
or,         m = 
                 =  
 
                 = 10 kg/s
Now, according to the steady flow energy equation:




 = 5 K
 = 5 K
 = 5 K + 300 K
 = 5 K + 300 K
 = 305 K
 = 305 K
            = (305 K - 273 K)
            = 
Therefore, we can conclude that the exit temperature of the gas in deg C is  .
.

Answer:
1123.6 pounds/ square inch.
Explanation:
Fluid pressure is the ratio of force or weight applied by the fluid per unit area.
i.e Fluid pressure = 
The maximum load of the jack is obtained at its maximum capacity = 5000 pounds
Area of the large piston on the jack = 4.45 square inches
Thus,
Fluid pressure = 
                         = 1123.5955
Fluid pressure = 1123.6 pounds/ square inch
Thu, the fluid pressure in the jack at maximum load is 1123.6 pounds/ square inch.
