This will depend on the standards followed, whether nfpa or bs or indian or....... Generally head calculation will involve the friction loss in piping + minimum required head at the hydrant / sprnkler as suggested by standards.

Hai,

For fire fighting system consisting of stand pipe systems, NFPA-14 std is applicable. Required end pressure is almost 5-6bar. You can use darcy weisch back's eqn for calculating the pressure loss.this formula is accurate in all cases. For average sized buildings, 10-11bar pump will be sufficient..
