Latihan<br />

Hitunglah debit untuk aliran melalui saluran trapezoidal<br />

dan setengah lingkaran dengan luas yang sama.<br />

A = (3) 1/2 y 2 = 3,21 m2 y = 1,36 m<br />

Rh = ½ y = 0,68 m<br />

Q = 1/n . A. R 2/3 . S ½<br />

= 1/0,015 . 3,21 . (0,68 ) 2/3 . 0,001 ½<br />

= 5,23 m3/det<br />

Debit aliran di saluran trapezoidal 4,6 % lebih besar<br />

daripada debit di saluran persegi.
