A square rapid mixing tank is used to process 0.14 m3/s of water. The depth of the tank is assumed to be 2 times the width. Use a detention time of 25 seconds and velocity gradient of 700 1/s. The properties of the water in the tank are the same as the ones listed in the formulas sheet.

Determine

a) The dimensions of the rapid mixing tank

b) The power input needed from the motor if its efficiency is 80%

Water (ρ = 999 kg/m3, μ = 1.3x10-3 N/s) from a large tank with P1 flows through a pipeline at the rate of 0.14 m3/s to atmosphere as shown. The pipe diameter of the entire piping system is 20 cm and material is cast iron. Knowing discharge velocity V2 is the same as the flow velocity in the pipe, no discharging nozzle loss, Kinlet = 0.5, and Kelbow = 1.1, calculate the absolute P1 (MPa) in the tank needed to...
