The flume is of unplaned boards, rectangular, 2.67 wide X 2.83 deep, with an inclination of 32 feet per mile. There are sharp curves, although these were made as regular as practicable; the boiling action of the water passing around these curves brought the flow line (Q = 32.8) nearly up to the top of the sides; with a straight flume of the same size, the water would have doubtless stood several inches lower.
Therefore:
a = 2.67 × 2.83 = 7.56 ;
Q = 32.8, hence
and n = 59.
