FALL 2018 - MIDTERM 1 - SOLUTION

PROBLEM 4

    a.

    The exponent of the discharge-area rating: β.

    b.

    Gravity, friction, pressure gradient, and inertia.

    c.

    W/D > 10

    d.

    They are both integrals of force, energy the integration in space, momentum in time.

    e.

    Under Chezy friction, in a wide rectangular channel the neutral-stability Froude number is 2.

    f.

    For Froude number = 2, under Chezy friction, the Seddon and Lagrange waves have the same celerity.

    g.

    The critical slope Sc has the same value as the fricion factor F.

    h.

    Minimum value of Manning's n: n = 0.008, applicable to acrylic plastic (lucite).
