A chemical feed pump at a water treatment plant is set to 40 percent of its total speed. The flow rate that the pump is
operating at must be determined to verify it is providing the appropriate dosages to the treatment processes. The effluent
of the pump is collected over a period of 5 minutes, and the volume of the effluent was measured using a graduated
cylinder. The volume was determined to be 245 milliliters. The pump’s flow rate is___.
a. 27 milliliters per minute (mL/min.)
b. 32 milliliters per minute (mL/min.)
c. 49 milliliters per minute (mL/min.)
d. 56 milliliters per minute (mL/min.)
