RE: (41) Bulk Cylindrical Tank
As someone who worked for a company that builds tanks I'm not surprised to see the example tank roof in Figure 25-5 is a spherical dome. The picture looks like an ellipsoidal roof, but equation 25-11 is the volume of a spherical cap.

While a hemisphere (R=r) could be used for a pressure vessel it's too expensive for a simple storage tank. An ellipsoidal roof (like the sketch seems to show) is also vey expensive and would again be typically limited to pressure vessels. An example of a pressure vessel with an ellipsoidal head is your BBQ propane tank.

However the roof volume will be wrong since the roof geometry specified is inconsistent.

Vo = R - sqrt(R² - r²) = 78 - sqrt(78² - 72²) = 48 inches

The paper states and uses Vo = 36", so the roof volumes will be wrong. Measurement 4 in Table 25-3 should be 13,321 gallons, and measurement 5 should be 13,521 gallons.
