Determine the dimensions of a rapid-mixing basin to process 12,000 m³/d of water. The basin will be square and the depth is assumed to be 1.5 times the width. Use a detention time of 30 s and velocity gradient of 700 s¹. The average minimum sustained temperature is 15°C and the absolute viscosity is 1.139 × 10-³ kg/(m.s). Two rapid-mixing basins will be constructed with each having the capacity to process the entire flow. Determine the following: a. Dimensions of L, W, and D (m). b. Power input (W).

Determine the dimensions of a rapid-mixing basin to
process 12,000 m³/d of water. The basin will be square
and the depth is assumed to be 1.5 times the width.
Use a detention time of 30 s and velocity gradient of
700 s¹. The average minimum sustained temperature
is 15°C and the absolute viscosity is 1.139 × 10-³
kg/(m.s). Two rapid-mixing basins will be constructed,
with each having the capacity to process the entire
flow. Determine the following:
a. Dimensions of L, W, and D (m).
b. Power input (W).
