Answer:

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 
where;
L = 6870
S = 5/264

min
Since 60 min = 1 hour
32.34 min will be (32.34*1)/60
= 0.539 hour
Lag time 


The time to peak i.e


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

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

where
484 = peak factor
Recall that A = 475 acres, to miles, we have:
A = 0.7422 mile²

∴


Answer:

Answer:
The name of the portal is School Bhuvan.
Explanation:
School Bhuvan is a portal that provides E-learning courses in Geospatial Technologies and Remote Sensing with a view to helping students know about countries and the natural resources that abound in them. School Bhuvan also reveals the roles which natural resources of a country play in sustainable development. To achieve these, this portal has an earth browser which gives a gateway to discovering and exploring virtual earth in 3D, 2.5D and 2D space.
Fossil fuel power plants burn coal or oil to create heat which is in turn used to generate steam to drive turbines which generate electricity. ... In 2017, fossil fuels generated 64.5% of electricity worldwide. These plants generate electricity reliably over long periods of time, and are generally cheap to build.
