1)                 
Put the water
into the storage tank to a nearly full level  
(about maximum 10cm  from the top
)                                       

2)                 
Check the flow
control value let V7 and V8 are closed

3)                 
Check the outlet
value is closed or not            

4)                 
Adjust the speed
to zero by adjusting the inverter

5)                 
Check all the
arrangement before starting the procedure                                

6)                 
open the flow
control value V7 to a nearly full open position to kick  out air and then turn it in closing direction
to obtain an output pressure 0.7(kg/cm^2)                                                                                                                                                             

7)                 
Record the speed
in rpm   

8)                 
Record the
discharge pressure p2

9)                 
Find flow volume
in liter                                                              

10)             
Note the time
period                                                                         

11)             
Find power input
In watt                                                              

12)             
After finding
the above                                                               

             slightly close the flow control value v7 to
increase the outlet pressure in steps with an increment f 0.2 kg/cm^2
respectively until a maximum pressure is reached (i.e v7) is fully closed    then record the same data as in the above
step of test  repeat the test at some
other speed such as 2500 , 2000, 1500 rpm and the data .
