Answer:
The power she can generate is 185.22 KW.
Explanation:
<h3><u>DATA</u></h3>
3.00m wide and 0.500m deep.
Cross sectional area = 1.500m^2
Velocity = 1.35m/s
Volumetric flow rate = Av = 18.00m^3/s
Mass flow rate = 18,000kg/s
Height = 4.20m
25.0% efficiency
<h3><u>
FORMULA:</u></h3>
P = dE / dt * eff
<h3><u>
SOLUTION:</u></h3>
18,000kg/s (9.8m/s^2) (4.20m) (25%) = 185,220 watts
= 185 kw
Answer:
v=0.94 m/s
Explanation:
Given that
M= 5.67 kg
k= 150 N/m
m=1 kg
μ = 0.45
The maximum acceleration of upper block can be μ g.
a= μ g ( g = 10 m/s²)
The maximum acceleration of system will ω²X.
ω = natural frequency
X=maximum displacement
For top stop slipping
μ g =ω²X
We know for spring mass system natural frequency given as
By putting the values
ω = 4.47 rad/s
μ g =ω²X
By putting the values
0.45 x 10 = 4.47² X
X = 0.2 m
From energy conservation
150 x 0.2²=6.67 v²
v=0.94 m/s
This is the maximum speed of system.
