Answer:
1072 acre foot
1331424000 kg
Explanation:
1 feet has 12 inches, so 2 in is 0.167 feet.
1 km^2 has 1 million m^2.
1 acre is 4074 m^2.
So, 1 km is 247 acres.
Then 26 km^2 is 6422 acres.
So, the volume of water is
6422 * 0.167 = 1072 acre-foot
Since one cubic meter of water has 1000 kg
One inch is 25.4 mm = 0.0254 m
One feet is 12 * 0.0254 = 0.3048 m
An acre-feet has a volume of
4074*0.3048 = 1242 m^3
And that is a mass of water of
1242 * 1000 = 1242000 kg/acre-feet
Therefore the mass of rainwater in the town is of
1072 * 1242000 = 1331424000 kg = 1331424 tons
Answer:
a)148.9hp
b)25.2kg

Hello!
To solve this exercise follow the steps below.
1. Find the power the generator needs to operate at 100Kw,
This is done by remembering that efficiency in a generator is the ratio between real power and ideal power.
where
α=generator efficiency =0.9
Wi=nominial or ideal efficiency=100Kw
Wr=real effiency
solving for Wr
the power that the combustion engine must deliver is 111Kw for the generator to deliver 100Kw, Now use conversion factor to know the value in horsepower
2. Find the engine supply power using the combustion engine efficiency definition
α=engine efficiency =0.35
Wo = output power
=111.11Kw
Wi = supply power
solving for Wi
3. use the calorific power of diessel (CP=45KJ /g) to find the mass flow, remember that the supply power is the product of the mass flow and the caloric power
Wi=m(CP)
m=mass flow
solving for m
4. The mass flow is the ratio between the mass consumed and the time (1h) in this way we can find the diessel consumed in one hour at full load
M=diessel mass consumed
m=M/t
M=mt
Answer:
current ia = 50 mA
Explanation:
given data
mesh-current analysis
current source in circuit = 50 mA
to find out
value of the current ( ia )
solution
we know here that in mesh-current analysis with independent or dependent current or contain only here one current source then
there value of the current will be
value of the current ( ia) = 50 mA
because value of current source is self indicated mesg current
so ia = 50 mA
