Head loss due to friction
Head loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system
Peak storm water run-off rate
The magnitude of the peak runoff rate is related to the frequency of occurrence; the higher the peak runoff rate, the less frequently it will occur
Nominal Moment Strength
Mn is the nominal moment strength of the member, Mu is the bending moment caused by the factored loads, and φ is the capacity reduction factor
Nominal Shear strength
It is the shear force generated on the structure due to the force imposed on a given cross-sectional area
Spread footing design method
It usually designed to use 3 ksi < f'c < 4 ksi, whereas modern structural members frequently use concrete between the range of 4 ksi < f'c < 8 ksi.
