A three-phase, 5-hp, 220-V, six-pole, 60-Hz induction motor runs at a slip of 0.025 at full load. Rotational and stray-load losses at full load are 5% of the output power. Calculate the power transferred across the air gap, the rotor copper loss at full load, and the electromagnetic torque at full load in newton-meters.
question 1a with the help of a labeled drawing discriminate between the first-stage biochemical oxygen demand bod and
Suppose 500 mg of dye was introduced into the plasma compartment. After reaching steady state, the concentration in the blood is 0:0893 mg cm3. Find the volume of the plasma compartment
Two equilibrium stages at 25C are used as shown in the following diagram. If 300 kg H2O/h is fed to each extraction unit, what fraction of the acetone in the feed solution would be removed and what would be the composition of the combined extract?
Also sketch the power triangles before and after the addition of C, and find the overall current drawn from the supply.
Forty-five kilograms of a solution containing 30 wt% ethylene glycol in water is to be extracted with furfural. Using Figures 4.14a and 4.14c, calculate:
(a) What is the minimum number of theoretical stages necessary to effect this separation? (b) What is the minimum extract reflux ratio?
The volume of each stirred tank is 40,000 liters. In passingthrough this system, by how much has the activity decayed? The reaction follows first order kinetics with a constant density
Find the magnitude of the force P, required by the person pushing the vehicle to give the car an acceleration of 1 ft./s^2. The coefficient of kinetic friction between the car and the street is (.25).
Principles associated with the theory of Creep and Viscoplasticity need to be identified and your understanding of these principles. Graphs, tables, calculation etc should be included for better illustration.
