Afuel gas containing 86% methane, 8% ethane, and 6% propane by volume flows to a furnace at a rate of 1450 m3/h at 15°c and 150 kpa (gauge), where it is burned with 8% excess air. calculate the required flow rate of air in scmh (standard cubic meters per hour).
a certain gas has a molecular weight of 30.0, a critical temperature of 310 k, and a critical pressure of 4.5 mpa. calculate the density in kg/m5 (b) if the gas obeys the law of corresponding states of this gas at 465 k and 9.0 mpa (a) if the gas is ideal and

false

because it does not have the potential to be entirely used up

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
