What is the Godrich formula?

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.
4637*root(50)[1-0.01*root(50)],
30465.7902 lpm,
convert to mld,
43.870 mld = 44 mld.

But it's a Huston's formula @Dhanu.

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 = 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.

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.

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