Answer:
The rate of irreversible loss will be "55.22 MW".
Explanation:
The given values are:
Elevation,
h = 120 m
Flow of water,
Q = 100 m³/s
Efficiency,
= 80%
i.e,
= 0.8
Efficiency turbine,
= 50 MW
Now,
Without any loss,
The power generated by turbine will be:
⇒
On substituting the values, we get
⇒
⇒
Power generated in actual will be:
=
=
Hence,
Throughout the piping system,
The rate of irreversible loss is:
=
=
=
Answer: 30joules
Explanation
voltage of battery =12volts
2.5coulombs is the same as 2.5ampere-seconds
Energy required =12V*2.5A-S
=30watts-seconds
Hence the required energy is equal to 30joules.
The answer is D hope this helps have a good day !!:)
Answer:
yes, this is true statement
Explanation:
given data
mass m1 = 5 kg
mass m2 = 1 kg
speed v = 5v
to find out
It is possible that after the impact A is not moving and B has a speed of 5v
solution
first we get here initial momentum that is express as
initial momentum = m1v1 + m2v2
initial momentum = 5×V + 1 × 0
initial momentum = 5V
and
now we get final momentum
final momentum = m2v2+ m1v1
final momentum = 1 × 5V + 5 × 0
final momentum = 5v
so here we can say momentum is conserved
so this is the case of pure elastic collision
so we can say yes, this is true statement
