Exercise (VI) Quiz question

Two streams of slurry enter a pump. The volumetric flow rate of stream 2 is 0.68 times and density is 1.16 times that of slurry no. 1 respectively. if density of slurry no.1is 1364 kg/m³ . Then mass flow rate (M₁) of slurry stream no.1is

  (A)              
  
  (B)                    

  (C)      

  (D)              

          
 is mass flow rate of slurry 2

One can derive the following equation expressing mass flow rates in terms volume flow rates and density of slurry

  

 and  mass flow rate of stream 1 and 2

  and  volume flow rate of stream 1 and 2 

 and   density of slummy 1 and 2.


Using above equation: .

  ‘B’ is correct.
