Calculating Air Pressure for 10-Meter Liftoff with Air Pump

[spark727]

Hi guys,
i need your help, in finding the right equation.

1.) I want to lift up a person including equipment 10m of the soild ground in 10 seconds.
2.) The persons weight (including equipment) is 120Kg
3.) The propoulsion will be press'd air (NOT hot turbine air), just by a conventional air pump.
4.) The presure output, will be 2 nossles, wit a diameter of 100mm each.

Now the question is:
A.) How many Bar air pressure of the air pump is required?
B.) How many cubic meter of air will be the output of the air pump

now my thought have been:

120Kg * 10m = 1200Kgm
= 120kg/1.293(1kg of air) = 92.80m3/s
= 92.80m3/s * 10m (high) = 928m3

1.) airpump air volume needed = 928m3?
2.) 120kg = (kg=L=Bar) = 120 Bar??
