QUANTUM COMPUTING - ANSWER 32.8 : (a) S = a | 00 > + b | 01 > + g | 10 > + d | 11 > = | 0 > ( a | 0 > + b | 1 > ) + | 1 > ( g | 0 > + d | 1 > ). (b) By comparison of S, a = b = g = d = 0.5. P(0) = a x a + b x b = 0.5 x 0.5 + 0.5 x 0.5 = 0.5, P(1) = g x g + d x d = 0.5 x 0.5 + 0.5 x 0.5 = 0.5.

Question 49 - According to rules of thumb in chemical process design, consider the use of an expander for reducing the pressure of a gas when more than 20 horsepowers can be recovered. The theoretical adiabatic horsepower (THp) for expanding a gas could be estimated from the equation : THp = Q [ Ti / (8130a) ] [ 1 - (Po / Pi) ^ a ] where 3 ^ 3 is 3 power 3 or 27, Q is volumetric flowrate in standard cubic feet per minute, Ti is inlet temperature in degree Rankine, a = (k - 1) / k where k = Cp / Cv, Po and Pi are reference and systemic pressures respectively. (a) Assume Cp / Cv = 1.4, Po = 14.7 psia, (temperature in degree Rankine) = [ (temperature in degree Celsius) + 273.15 ] (9 / 5), nitrogen gas at Pi = 90 psia and 25 degree Celsius flowing at Q = 230 standard cubic feet per minute is to be vented to the atmosphere. According to rules of thumb, should an expander or a valve be used? (b) Find the outlet temperature To by using the equation To = Ti (Po / Pi) ^ a.
