Hello,
Was wondering if anybody could help with the following question as I am struggling, and this area is not my strong point. Note this is not homework purely self-study, out of curiosity to help me understand the subject area in more detail.
In each minute a pump draws 2.4m^3 of water from a well 5m below ground, and issues it at ground level through a pipe of cross sectional area 50cm^2. Find a) the speed at which the water leaves the pipe, b) the rate at which the pump is working. If in fact the pump is only 75% efficient (i.e. 25% of the power is lost in the running of the pump), find the rate at which it must work.
A solution with some commentary would be absolutely brilliant.
Many thanks to whom can help.
