The line builder recorded the highest sound pressure level at 80.3 dbA at 1 foot, 77.6 dbA at 3 feet, 72.1 dbA at 6 feet, and
68.4 dbA at 9 feet. The other sources of noise in the kitchen were all below 80 dbA. Although all sound pressure level
measurements were below the threshold value of 85 dbA defined by Ontario Regulation 381/15, the reading of 80.3 dbA at 1
foot from the line builder would require preventive measures and an investigation in the future. The total sound pressure
levels for the line builder and the exhaust fan were calculated separately. The total sound pressure level in the line builder
was 80.3 dbA, while the whole sound pressure level in the exhaust fan was 72.4 dbA. The presence of another source of
noise with the dishwashers has resulted in a minor increase in the line builder, as can be seen. The resulting total sound
pressure levels reached 80.3 dbA, supporting the need for further investigation.

As an environmental engineer working for a consulting company you were asked to evaluate an
existing water treatment plant for possible upgrade. One of the treatment unit processes you
evaluated was the rapid mix tank. You had the following information.
2.
Current average water flow rate 15 x 10' m'/d.
Projected flow rate in 20 years 24 x 10' m'/d.
Temperature of water varies from 12 to 20° C.
No. of rapid mix tank = 1
Dimension of tank: water depth 2.1 m, width 2.1 m, length 2.1 m
Tank is not baffled:
Mixer is 4-bladed turbine with 45° pitched blade (N, = 1.27)
Diameter of impeller 0.9 m
Label on the motor:
horsepower of motor 10 hp (1 hp 746 watts)
rpm of blades = 120 rpm (assume a motor efficiency of 80%)
Evaluate whether the rapid mix system
(1) Is sufficiently designed for current use? If not, provide some remedies.
(i) Will the current system be sufficient for the projected flow rate in 20 years?
If not, what are some of your suggestions or additions to meet the projected flow?
