Yeah I agree with @Dip.
Because in the Godrich formula, there is only time and population variables are there. In that equation, there is no fire demand quantity that can be calculated.
If I'm wrong then correct me!
Thanks.

Godrich formula:
Q = 4637 (P)^.5 ( 1 - 0.01 (P)^.5 )
P - population in thousands,
Q - lt / hr.
Q = 4637 (50)^.5 ( 1 - 0.01 (50)^0.5 ) * 24*60.
Lt/ day,
= 44mld.
Q = 4637 (P)^.5 ( 1 - 0.01 (P)^.5 )
P - population in thousands,
Q - lt / hr.
Q = 4637 (50)^.5 ( 1 - 0.01 (50)^0.5 ) * 24*60.
Lt/ day,
= 44mld.

Goodrich's formula. P = 180*t^ (-0.1),
P = Population in thousand.
t = time in days.
Goodrich's formula is to find the peak demand for water not for fire demand.
P = Population in thousand.
t = time in days.
Goodrich's formula is to find the peak demand for water not for fire demand.

Goodrich's formula.
P = 180*t^(-0.1),
P = Population in thousand.
t = time in days.
Goodrich's formula is to find the peak demand for water. Not for fire demand.
P = 180*t^(-0.1),
P = Population in thousand.
t = time in days.

Nothing using under writer formula only,
4637*root(50)[1-0.01*root(50)],
30465.7902 lpm,
convert to mld,
43.870 mld = 44 mld.

43.870 mld = 44 mld.

Godrich's formula is to find the fluctuation of water demand it's not for finding the fire demand.

Goodrich formula.
P =1.8(t)^-0.1.
P - peak demand.
t - time in days.
P =1.8(t)^-0.1.
P - peak demand.
t - time in days.

@Chetan.
It's not Houston's formula. It's is a Boston's formula.

Generally, for 50 lakh population, the fire demand is 1lpcd.

@Ismaeel.
Millions of a liter per day = MLD.
Millions of a liter per day = MLD.
