Capitolo 45

depth of water of 20 in, two sets of the calculations are in demand.
Before 20 in depth on the incision 6 in wide, and then 4 in depth
on the incision, 28 in less 6 in, or 1 wide ft.

       ____ _____
(1) the C \ / H^3 = 4.69/2 \ / 10^3 = 2.345 xes 31.62 = 74.15
       ____ ____
(2) the C \ / H^3 = 1.0 xes 4.69 \ / 4^3 = 1.0 xes 4.69 xes 8 = 37.52

You add in c.  ft for min = 111.67

The I unload actual it would slightly be in excess of this.

Besides the circumstances it already enumerated what
strikes the accuracy of gaugings taken from he/she wants to say of a sheltered dam
in a sewer it is also the fact that sewage's approaches
the dam with a speed to which various notably from duration
time. To manufacture check for this the head calculated
to produce the speed has to be assistant to the actual head. This
you/he/she can be incarnate in the formula, as, for example, Ripple of Saint
formula for unloaded standing cubic for minute, with H it measured
standing, you/he/she is written

instead of the usual form of
       ____
  195 \ / H^3 that is used

when there is not any speed to consider. The V
it represents per second the standing speed.

Triangular or incisions of V are usually formed so that the angle
among the two sides it is 90, when the width to some point
it will be twice always the measured vertical height to the
centre. The I unload in this case it varies as the square root of
the fifth power of the height instead of the third power as
with the rectangular incision. The reason for the change of
power is on that _approximately_s the I unload an incision
with some head determined various as the cross-sectorial area of the
body of water that passes him/it on. The 90 incision area is
half that of a rectangular incision that circumscribes, so that the
discharges of an incision of V it is approximately equal to that of a
rectangular incision that has a fifty-fifty equal ampleness the ampleness of the
Incision of V to level of water, and as the total ampleness it is equal to
the depth of water that passes on the incision the half ampleness doubles
