Question 16.8: For the vessel described in Example 16.7, determine the flui...

Fluid pressure head is needed at both the lower shell-to-head tangent line and the lowest point of the lower head.

At the lower shell-to-head tangent line, the fluid height is 30 ft+2.5 ft=32.5 ft.

For fluid  P_{ f }=\frac{(32.5)(35)}{144} =7.9 psi

For water  P_{ f }=\frac{(32.5)(62.4)}{144} = 14.1 psi

At the bottom of the lower head, the fluid height is 30 ft+5 ft=35 ft.

For fluid  P_{ f }=\frac{(35)(35)}{144} = 8.5 psi

For water  P_{ f }=\frac{(35)(62.4)}{144} = 15.2 psi
