I am doing a mine engineering degree by correspondence and I have an assignment to do and the lecture notes do not provide any assistance on some of the cals.

I am hoping some of you can help me

I will start with these two questions and see if you can help before posting more:

Q1)

Determine the reqired power to pump 11.36 l/s against a total dynamic head of 112.78m if the pump operates at 70% efficiency

Q2)

What is the required power to pump 4000 litres per minute against a total dynamic head of 120m if the pump operates at 75% efficiency

The formula the notes gives me is

P = Q.γ.H / 10 power 6

But I can't work out what this means
