A buried stainless steel nuclear waste storage tank contains significant amounts of dissolved radioactive Cr3+, Al3+, Fe3+ and Ni2+ at pH 2. It is proposed to neutralize this acid tank solution to pH 7 in the tank with concentrated NaOH. The neutralised solution will then be pumped out of the tank for transport to other facilities for further processing. Explain the advantages and disadvantages of the neutralization step using appropriate Pourbaix diagrams. On the basis of your evaluation, would you recommend neutralization?
Analyze the synchrounous circuit with input X and output Z constructed with two flip flop of JK type with outputs QA and QB. The flip flop input exciatation are as follows: JA=XQB; KA=0; Jb=XQA'; KB=QA. the output equation is Z=XQB'.

The common crystal used in older color teleisions outputs a 3.58002 MHz signal. What is the MOD number required for a counter to reduce this to a 60Hz output
A 50 Hz, 440 V, 3-phase , 4-pole induction motor develops half the rated torque at 1490 r.p.m. with the applied voltage magnitude remaining at the rated value, what should be its frequency if the motor has to develop the same torque at 1550 r.p.m.
At the instant shown, car A has a speed of 20km/h, which isbeing increased at a rate of 300km/h2 as the car entersan expressway. At the same instant, car B is decelerating at250 km/h2 while traveling forward at 100 km/h.
a 4-pole, 50 hz induction motor has a full load slip of 5%. each rotor phase has a resistance of 0.3 ohms and a standstill reactance of 1.2 ohms. find the ratio of maximum tirque to full load torque and the speed at which the maximum torque occurs..
