Mechanical Operations For a turbine agitated and baffled tank, operating at low Reynold's number (based on impeller diameter), the power number (Np) varies with NRe as Np ∝ NRe Np ∝ √NRe Np → constant Np ∝ 1/NRe Np ∝ NRe Np ∝ √NRe Np → constant Np ∝ 1/NRe ANSWER DOWNLOAD EXAMIANS APP
Mechanical Operations Pick out the wrong statement pertaining to the roll crushers. For hard material's crushing, the reduction ratio should not exceed 4 Both the rolls run necessarily at the same speed Reduction ratio and differential roll speed affect production rate & energy consumed per unit of surface produced Maximum feed size determines the required roll diameter For hard material's crushing, the reduction ratio should not exceed 4 Both the rolls run necessarily at the same speed Reduction ratio and differential roll speed affect production rate & energy consumed per unit of surface produced Maximum feed size determines the required roll diameter ANSWER DOWNLOAD EXAMIANS APP
