a rural kansas watershed that is ungauged has an area of 475 acres and a main channel length of 6870 feet with an average slope

dlinn [17]

Answer:

$\mathbf{Q_p =682 \ \ ft^3/s}$

Explanation:

Given that:

Area = 475 acres

The length of the channel (L) = 6870 feet

The average water shield slope (S) = 100 feet/mile

Since; 1 mile = 5280 feet

Burst duration D = 15 min

∴

100 feet/mile = 100/5280

The average water shield slope (S) = 5/264

Using hydrograph method:

The time of concentration $t_c = 0.0078L^{0.77} S^{-0.385}$

where;

L = 6870

S = 5/264

$t_c = 0.0078(6870)^{0.77} (\dfrac{5}{264})^{-0.385}$

$t_c =32.34$ min

Since 60 min = 1 hour

32.34 min will be (32.34*1)/60

= 0.539 hour

Lag time $T_l = 0.67\times t_c$

$T_l = 0.67\times 32.34$

$T_l = 21.6678\ min$

The time to peak i.e

$T_p = \dfrac{D}{2}+ T_L \\ \\ T_p = \dfrac{15}{2}+ 21.6678 \\ \\ T_p = 29.168 \ min$

$T_r = \dfrac{T_p}{5.5} \\ \\ T_r = \dfrac{29.1678}{5.5} \\ \\ T_r = 5.30 \ min$

Since D = 15 min is not equal to $T_r$ , then we hydrograph apart from $T_r$ duration lag time.

Then;

$T_p \ ' = T_p + \dfrac{D-t_r}{4} \\ \\ T_p \ ' = 29.168 + \dfrac{15-5.30}{4} \\ \\ T_p \ ' = 31.593$

Now, we need to determine the peak discharge $Q_p$ by using the formula:

$Q_p = \dfrac{484 \times A}{T_p \ '}$

where

484 = peak factor

Recall that A = 475 acres, to miles, we have:

A = 0.7422 mile²

$T_p \ ' = 31.593/60$

∴

$Q_p = \dfrac{484 \times 0.7422}{\dfrac{31.593}{60}}$

$\mathbf{Q_p =682 \ \ ft^3/s}$

You are at the aquarium looking at a freshwater mammal tank and a manatee swims close to the glass. On his front flippers you se

SashulF [63]

The fingernails on the manatee are homologous structures.

Explanation:

The manatee is an animal that lives in the water, but it is not an animal that is related to the fish, instead it is a mammal. When the term mammal is mentioned, people often think of terrestrial animals, but some of the mammals are not living in the water, and have lot of characteristics that are very similar to the other marine animals. Mammals that live in water are:

manatee
whales
seals
walrus

Some of these mammals, like the manatee, actually have fingernails, which is very weird considering that they are of no use. The fingernails are actually homologous structures, or rather structures that have been kept from their ancestors, and can be found at many other animals with which they share common ancestor. While the ancestors of the manatee were terrestrial mammals, over time they totally transformed as they were using the water more and more, but the fingernails remained, with the main reason for that being that they are not disadvantageous, so there is no evolutionary pressure for the animal to lose them.
