Let _x_ = velocity of flow in 16-in. pipe, in feet per second, then 2.56
_x_ = velocity of flow in 10-in. pipe, in feet per second.

From which:


13,200 47,500
------- + ------- = 13,800
2.56_x_ _x_

_x_ = 3.805

and 2.56_x_ = 9.740


The discharge is:


For the 16-in. pipe, 1.396 x 3.805 = 5.31 cu. ft. per sec.;
and, for the 10-in. pipe, 0.5454 x 9.74 = 5.31 cu. ft. per sec.


The question arose as to whether or not the particles of bran in the
water traveled as fast as the water flowed. It was also desired to check
by observation the relative velocities in the two pipes, as above
deduced.
