F(N) = 10^(N-1) minus the sum of k=1 to 10^(N) of 0.1. Work out (by hand) the exact value of f(N). Work a MATLAB function with a for loop to execute f(N). I can’t figure out how to find the exact value of this and so I can’t figure out how to format it for the for loop. I have tried and can’t find any documentation that clears it up for me. Please help.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
