From FM 5-482, Figure C-8 f=.0216

Next, determine d5

8.4155 = 42,196

So, Hf= .031 x 4000 x 490,000 = 1,312,416

42,196

Finally, you find the total headloss due to friction, Hf= **31 feet**.

f. Advanced Hydraulics Mathematics. Now you have a basic understanding of the reason for

pipelines, and general characteristics and properties of petroleum fluids. Next we will attempt to

familiarize you with some of the advanced petroleum math computations that will help you in your

future petroleum assignments. Specifically, you will be able to calculate volume correction, feet of

head, flow velocity, flow type, and head loss.

(1) You must be able to quickly apply each principle you have learned thus far before you can

begin to physically design a pipeline or hose line. Therefore, a thorough problem solving exercise must

be completed. Let us begin:

(a) Volume Correction to 60F: Volume correction is the correction of measured quantity

of product to the net quantity of product at 60€F after deducting bottom sediment and water.

(1) After determining API at 60€F, and using the average temperature of the

product (measured during gaging) in the tank, correct the fuel volume by using a volume correction

factor obtained in ASTM Table 6B. The correction factor (CF) is used as a multiplier.

(2)

Corrected volume = (Innage - BS&W) x CF

Calculate the corrected volume at 60€F

Data: Innage = 24,816 gallons

BS&W = 240 gallons

API @ 60F = 58.5

Avg Temp = 70€F

SOLUTION: CF = .9932 (TABLE 6B)

Corrected volume = (24,816 - 240) x .9932

=24,576 x .9932

= 24,409 gallons

(b) Feet of Head: The measure of pressure in terms of height of a column of a given fuel

is known as feet of head (HL).

Pressure (PSI) = Height (ft) x SG

Height = 2.31 x Pressure
