Refer to Q7, and determine the agitated batch liquid Reynolds number. (ρB = 64.0 lbs./cu. ft. and μB = 2.12 lb./hr-ft.)

(a) 977,035

(b) 900,045

(c) 877,035

(d) 800,045

This question was posed to me in an international level competition.

I want to ask this question from Power Requirements for Mixing topic in section Fluid Flow and Mixing of Bioprocess Engineering

Best answer
Right choice is (a) 977,035

Explanation: NRe = Reynolds number for agitated liquids = ( D^2 * N * ρB / μB).

NRe = (3.02 * 3,600 * 64.0 / 2.12)

NRe = 977,035.
