This document discusses calculating the characteristics of flow in an open channel based on given parameters including width, depth, slope and velocity. It determines that the flow is 1.289 times critical (supercritical) based on calculations of area, wetted perimeter, hydraulic radius and Froude number.

Diketahui :

b = 6.00 m
m =0,40m
h = 1,40m
v = 0,45m/dt
Ditanya: Apa macam alirannya?

Suhu = 26oC

Jawab:
P =b + 2 x h 1 + m2
=6 + 2 x 1,40 1 + 0,402
= 6 + 2,80 x 1,0770

= 8,544
= 9,184
R = A/P

= 6 + 3,0156

=9,184/9,016

= 9,0156

=1,01863

=9,016 meter

= 1,019 M

T = b +2hm

D = A/T

= 6 + 2 x 1,40 x 0,40

= 9,184/7,12

= 6 + 1,12

= 1,289

= 7,12 meter
A = (b + T) x h

Z = A D
= 9,184 1,289

= (6 + 7,12) x x 1,40

= 9,184 X 1,1353

= 13,12 x 0,7

= 10,42697
