Filtrate flow rate in case of a rotary drum vacuum filter (in which Rm < < Rc) is proportional to ____________ and the cycle time (where, μ = filtrate viscosity Rm = filter medium resistance Rc = cake resistance)?
Correct answer: B. 1/√μ
- A. √μ
- B. 1/√μ
- C. 1/μ
- D. 1/μ2
Explanation
With filter-medium resistance negligible compared with cake resistance, the filtration rate varies inversely with the square root of filtrate viscosity, so it is proportional to 1/√μ. The cake controls the pressure drop in this case.
