It is desired to design a packed tower for continuously absorbing nh3 from air by a countercurrent water flow in an absorption tower using the following data: l' #41 = .05 0.000512 201bmol of air ht ft2 ; vol . flow rate= 108,000 ft3 of gas entering at 27°c and 1 atm hr equilibrium relationship: y=0.8 x ; kya-10 ibrnol nh3 per (hr-ft*) 19.2 lbmol nha (hr ft3) calculate: a. mass flow rate of entering gas in lbmol/hr b. mass flow rate of nh3-free air entering in lbmol /hr c. xi concentration of ammonia in the leaving water stream d. l'㎜ e. diameter of tower and superficial velocity of gas flow. f. height of packed section

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

answer; natural resources;

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
