Calculating Water Pumping Requirements for River-to-Dam System

[pushpull]

How is following calculated ?
Pumping water from river, up a hill 100 metres high, it then runs downhill into a dam.
Need to deliver 100 megalitres a day, the pipe will be concrete lined steel and the distance about 25 km.
What is total head required from the pump and what is the electrical power needed.

Is this homework? You will have to show what you've tried so far, because it's not ethical for us to simply solve the problem for you.

And you need to know what the elevation of the dam is too...

Agreed with Mech. btw you're also going to need a pipe size for velocity and subsequent head loss calcs.
