The average flow speed in a constant-diameter section of the alaskan pipeline is 2.5 m/s. at the inlet, the pressure is 8.25 mpa (gage) and the elevation is 45 m; at the outlet, the pressure is 350 kpa (gage) and the elevation is 115 m. calculate the head loss in this section of pipeline.

head loss = 805.327 m

Explanation:

given data

average flow speed v = 2.5 m/s

inlet pressure Pi = 8.25 MPa

elevation Zi =  45 m

outlet pressure Po = 350 kPa

elevation Zo = 115 m

we consider oil Specific Gravity = 0.92

to find out

head loss in this section of pipeline

solution

we find here head loss that is inlet and outlet  

Hi =    ..............1

put here value  

Hi =

Hi = 959.425 m

and

Hout =    ..............2

put here value  

H out =  

H out = 154.098 m

so  

head loss is = Hi - H out  

head loss is = 959.425 - 154.098  

head loss = 805.327 m

can you make it more obvious. i can't see it properly
