Abinary mixture is to be fed a continuous distillation column. calculate the minimum number of trays required to achieve a separate from 4 mole percentage to 96 mole percentage distillate in a binary column with alpha 2.5

minimum number of trays:

N = 7 trays

Explanation:

minimum number (N):

∴ α = 2.5

∴ Xd = 0.96molar fraction the distillate

∴ Xb = 0.04 molar fraction in the bottoms

⇒ N = ( Log  ( ( 0.96 / ( 1 - 0.96 ) ) * ( ( 1 - 0.04 ) / 0.04 )) ) / Log ( 2.5 )

⇒ N = 6.94 ≅ 7 trays

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
