STEP 1: Convert Input(s) to Base Unit

Factor of Friction: 1.148 --> No Conversion Required
Length of Packaged Bed: 1100 Meter --> 1100 Meter No Conversion Required
Superficial Velocity: 0.05 Meter per Second --> 0.05 Meter per Second No Conversion Required
Void Fraction: 0.75 --> No Conversion Required
Acceleration due to Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required
Diameter(eff): 24.99 Meter --> 24.99 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_f = (f_f*L_b*U_b^2*(1-∈))/(g*D_eff*∈^3) --> (1.148*1100*0.05^2*(1-0.75))/(9.8*24.99*0.75^3)

Evaluating ... ...

H_f = 0.00763903444975874

STEP 3: Convert Result to Output's Unit

0.00763903444975874 Meter --> No Conversion Required

FINAL ANSWER

0.00763903444975874 ≈ 0.007639 Meter <-- Head of Fluid

What is internal flow?

Internal flow is a flow for which the fluid is confined by a surface. Hence the boundary layer is unable to develop without eventually being constrained. The internal flow configuration represents a convenient geometry for heating and cooling fluids used in chemical processing, environmental control, and energy conversion technologies.
An example includes flow in a pipe.
