Question about pump calculation?



experiment on the new electric pump to extract oil from the engine, how do i find the value of the head(m) of the pump?
given data for the pump:

12 volt dc pump
60 watts
flow rate of 3 liter/ minutes
using 7mm inner diameter tube
both intake and outtake tube has 2meter in length

the position of the pump is jut beside the extraction tank, so how i can determined the value of the head(m) so i can calculate the WHP and the pump efficiency??
