The distance and depth values measured in various slices in a
stream section and the measurement times and rotation numbers in a
muline with coefficients a = 0.15 and b= 0.08 are given
below.
a. Calculate the area, average velocity, and flow rate of each
slice as well as the total area and average velocity of the entire
cross section.
b. When measuring with another muline, it was measured as n = 22
when V = 1.94 m/s and n = 28 when V = 2.14 m/s. Determine
coefficients of muline and equation of velocity. In a measurement
made with this muline, calculate the flow rate according to making
35 rotations to the muline in 55 seconds.
