Browse complete papersWhy is compressive strength usually measured in the field instead of tensile strength?
Tensile strength is always higher
Compressive strength is easier and more convenient to test
Tensile strength does not affect structural design
Compressive strength is always independent of water-cement ratio
Correct answer
Tensile strength is always higher
Which of the following is the correct expression for the Darcy-Weisbach equation in fluid flow?
\(\Delta P = \rho gh\)
\(\Delta P = f * (L/D) * (\rho v^2 / 2)\)
\(Q = A * v\)
\(\Delta P = (\rho * g * h) / A\)
Correct answer
\(\Delta P = \rho gh\)
