You are comparing distillation column designs at 1 atm and 3 atm total pressure for a particular separation. You have the same f

eed in both cases, and the feed is a saturated liquid in both cases. The product specifications do not change, and the same reflux ratio is used in both cases.
Compared to the design at 3 atm, the design at 1 atm will have: (Select one)a) more stages, fewer stages, the same number of stagesb) a larger diameter, a smaller diameter, the same diameterc) a higher reboiler temperature, a lower reboiler temp, the same reboiler temp

Answer:

more number of stages will be required , a smaller diameter , a higher reboiler temperature

Explanation:

It is stated in the question that the product specifications and the reflux ratio do not change.

The pressure in a distillation column varies:

  • directly as the diameter of the distillation column
  • inversely as the number of stages required for the design
  • inversely as the temperature of the reboiler

Based on the theory stated above, the distillation column design at a pressure of 1 atm requires a more number of stages than the design with 3 atm, it has a smaller diameter than the design at 3 atm. It also has a higher reboiler temperature than the design with 3 atm.

Elanso [62]
Y = a (b)^t/p

y is total money

a is original amount

b is growth / decay factor

t is time

p is the frequency of every growth or decay

15131.76 = 11613 x 1.08^x

15131.76 / 11613 = 1.08^x

A reciprocating compressor takes a compresses it to 5 bar. Assuming that the compression is reversible and has an index, k, of 1
Gelneren [198K]

Answer:

final temperature is 424.8 K

so correct option is e 424.8 K

Explanation:

given data

pressure p1 = 1 bar

pressure p2 = 5 bar

index k = 1.3

temperature t1 = 20°C = 293 k

to find out

final temperature  t2

solution

we have given compression is reversible and has an index k

so we can say temperature is

\frac{t2}{t1}= [\frac{p2}{p1}]^{\frac{k-1}{k} }  ...........1

put here all these value and we get t2

\frac{t2}{293}= [\frac{5}{1}]^{\frac{1.3-1}{1.3} }

t2 = 424.8

final temperature is 424.8 K

so correct option is e

An inductor has a 50.0-Ω reactance when connected to a 60.0-Hz source. The inductor is removed and then connected to a 45.0-Hz s
nignag [31]

Given:

X_{L} = 50.0 \ohm

frequency, f = 60.0 Hz

frequency, f' = 45.0 Hz

V_rms} = 85.0 V

Solution:

To calculate max current in inductor, I_{L(max):

At f = 60.0 Hz

X_{L} = 2\pi fL

50.0 = 2\pi\times 60.0\times L

L = 0.1326 H

Now, reactance X_{L} at f' = 45.0 Hz:

X'_{L} = 2\pi f'L

X'_{L} = 2\pi\times 45.0\times 0.13263 = 37.5\ohm

Now, I_{L(max) is given by:

I_{L(max) = \sqrt {\frac{2V_{rms}}{X'_{L}}}

I_{L(max) = \sqrt {\frac{2\times 85.0}{37.5}} = 2.13 A

Therefore,  max current in the inductor, I_{L(max) = 2.13 A
