The quantity of water for foam production can be calculated from the following formula:

• Q1=A x R x T

• Q= Q1 + Q2

• Q= Q1 x Q2

• Q1= A + R + T

The water required for control in the practical critical area, may be expressed in the following formula:

• Q1=AxRxT

• Q2=AxRxT

• Q=Q1+Q2

• Q2=Q+Q1
