Answer
given,
discharge rate from pipe = 1000 gallons/minutes
now,
flow rate in cubic meters per second
1 gallon = 0.00378541 m³
1 min = 60 s
Q =
Q = 0.063 m³/s
flow rate in liters per minute
1 gallon = 3.78541 L
Q =
Q = 3785.41 m³/min
flow rate in cubic feet per second
1 gallon = 0.133681 ft³
1 min = 60 s
Q =
Q = 2.23 ft³/s
