Water energy Flashcards
1
Q
Eulers turbine equation (angular)
A
P = angular momentum * Torque
= angular momentum * density * flowrate *(r1 * vt1 - r2vt2)
2
Q
Eulers turbine equation (Angular whatever)
A
L = mr^2(vt/r) = mrvt
3
Q
Power
A
P = F*v
4
Q
Power from a dam
A
P = flowrate * density * 9.81 * height
5
Q
Potential energy of water
A
E pot = mgh
6
Q
Velocity of a shallow water wave
A
c = sqrt(g*h)
7
Q
Power of wave
A
(volume * density * 9.81 * height) / time
8
Q
Power from a tidal barage (inflow and outflow)
A
P = W/T = (2gpAh^2) / 2T
9
Q
Velocity of a deepwater wave
A
c = sqrt((gwavelenght)/(2pi))
