Derive a new expression of the time to empty a water tank. Now you must consider an energy loss at the hole, with the form h = k. Use k-1.5. Express the formula in terms of the tank surface area A₁ and the hole area A₂. Build the formulation and try to solve for the integral to get the final expression. Hint: Note that the Bernoulli will be B₁-B₂+hs

Equilibrium and Support Reactions

Civil engineers deal with structures that are composed of several members connected or with individual members such as beams and columns. To analyze such structures, the condition of statics must be applied. Under the static condition, the members are considered to be in equilibrium under the action of forces, that is, the members are assumed to be having negligible velocity.
