Estimating Energy Generated by Niagara Falls

[physics(L)10]

Homework Statement

Estimate E generated by water falling over Niagara falls in 5 day.
Height = 150m
Water flow =10⁴m³/sec
t=5x24x60x60=4320000sec

Homework Equations

P=W/t
mgh=mv²/2

The Attempt at a Solution

Work=mgh=m(9.8)(150)
Time=432000seconds
P=m(1470)/4320000

I just don't know how to convert 10⁴m³/sec into a mass

 

[ATOMatt]

The density of water is ~1000kgm$$^{-3}$$.

You can use this to work out the mass flowing per second.
