Question 3. A lake discharges into a steep channel. At the channel entrance the lake is 4 m above
the channel bottom. Neglecting losses, find the discharge for the following geometries:
(a) Rectangular section, b = 4 m
(b) Trapezoidal section, b = 3 m, angle = 60°
(c) Circular section, d = 3.5 m.
Question 7.
A popular sharp-crested weir for use in low-flow situations is the V-notch weir, as shown below.
When these weirs are designed, the equation for determining the flowrate by neglecting the
velocity head of the upstream flow can be written as Q = CH", where C is a coefficient of discharge
and is a function of the notch angle (0) and n is a weir constant. The constants C and n must be
determined experimentally for a given weir. In logarithmic form, the weir equation is log Q = n
log H + log C.
Assume we have a flume in the lab where we can experimentally explore the relationship between
Q and H for this weir by adjusting the flowrates. Develop an appropriate experiment to determine
n and C' (the weir discharge coefficient) for the weir used. Write the experimental procedure steps
and measurement readings that are needed to determine these coefficients empirically. Hint: Please
refer to your lab manual.

They all start working at D at Q (e.g., Q-8am). If a person departs at time t, assume the time needed to go from O to D is given by c(t)=A+Bx(t), where x(t) is the flow of people departing at time t [car/unit of time]. In addition, a is the penalty for being early at work (E(t) is how early the person arrived when departing at time t), and ẞ is the penalty for being late at work (L(t) is how late the person arrived when departing at time t). Assume 0 < a < 1 < ß. Further assume the departure time choice problem under the equilibrium conditions. Prove that the arrival time of people who depart when most of the M people start their trips is equal to Q.arrow_forward
