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.

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

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

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

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

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.

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.

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.
