A squirrel-cage induction motor operates at a slip of 0.05 at full load. The rotor current at starting is five times the rotor current at full load. Neglecting stator resistance and rotational and stray-load losses, and assuming constant rotor resistance, calculate the starting torque and the maximum torque in per-unit of full-load torque, as well as the slip at which the maximum torque occurs.
Also find the source voltage that would yield I = -8µA.
What is the composition by mass percent of the original mixture? Explain in detail how you arrived at this answer, writing down every step to the solution.
A paper by Ruckenstein and Tsai (1981)* shows that an "optimum pore size" can exist for catalytic reactions of large solute molecules in solvent-filled pores. Obtain the paper from your library and read it carefully. Then derive the analytical equati..
