Pressure drop field survey

An engineer has been assigned to check a kerosene process line for AP. The chief operator suspects the line is partly plugged (see Fig. 48.1)  

Kinematic viscosity of kerosene is 0.6 cSt. Therefore, viscosity is not a critical factor because it is less than 5 to 10 cSt. 

Note that centistokes = centipoise divided by density. The density in this case is approximately 0.9g/cm.  

Note that the 2.31 factor is the height in feet of a column of water that will exert a pressure equal to 1 psi, and atmospheric pressure 14.7 psi is equivalent to a height of approximately 30 ft of water. 

The actual flowing pressure loss corrected for elevation is then
