Example 34.4. A 3-$\phi$ induction motor is wound for 4 poles and is supplied from 50-Hz system. Calculate (i) the synchronous speed (ii) the rotor speed, when slip is 4% and (iii) rotor frequency when rotor runs at 600 rpm. (Electrical Engineering-1, Pune Univ. 1991) Solution. (i) $N_s = 120f/P = 120 \times 50/4 = 1500$ rpm (ii) rotor speed, $N = N_s(1-s) = 1500(1-0.04) = 1440$ rpm

3. The unknown acid is either acetic acid, $HC_2H_3O_2$, carbonic acid, $H_2CO_3$, or citric acid, $H_3C_6H_5O_7$. Based on the mole ratio from question 1, which one of these three is the unknown acid? 4. Write the balanced chemical equation for the reaction between the identified acid and sodium hydroxide. 5. Provide the structure formula for the identified acid (hand drawn or cut and pasted from a web image). Identify the hydrogen atom(s) given off as H$^+$ ions (protons) which give this substance its acidic character (circle the acid hydrogen(s) in the structure).
