In order to measure flow rates for the flow section in Figure 1, a propeller type current meter is
used for which calibration equation is V((m)/(s))=0.05n-0.5. Where n is the number of the rotation
of propellers. Using the measured rotations in Table 3
Figure 1: Cross section and measurement points.
Table 3: Propeller readings
aQ=K(h-h_(0))^(n), determine the parameters K,h_(0)
and n, graphically. Note that h is water depth, h_(0) is initial water depth, Q is flow rate
