# Rate question?

Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. Hi,

My physics question says A power station needs to get rid of energy at a rate of 600MW - would I assume this is 600MW per second? The velocity of the river to which the energy is transferred is given in ms^-1 if that helps.

Think about the units, Watts are defined as Joules per second, thus there is no need to make any assumption about the rate, as its given to you.

Hope this helps
