In this answer is already done just you need to explain the table how the table is made for both parts $($a$)$ and $($b$)$ and don't give different answer as this answers are correct.a$)$ Calculate the flow of gas in pounds per minute at the point of injection $($implies total flow rate, including $C{O}_2)$ if the gas upstream is

point of injection is $100\%C{H}_4.$

b$)$ Unfortunately for you, the gas upstream of the point of injection of $C{O}_2$ already contained $1\mathrm{.}0\%C{O}_2.$ How much was your origini

estimate in error $($in percent$).($again$,$ this implies total flow rate$)$

ent for and ansYour boss asks you to calculate the flow through a natural gas pipeline. Since it is $26$ inches inner diameter, it is impossible to run the gas through any kind of meter or measuring device. You decide to add $100$ lb of CO$2$ per minute to the gas through a small $(1)/(2)$ in$.$ piece of pipe, collect samples of the gas downstream, and analyze them for CO$2.$ Several consecutive samples after $1$ hour are:

$1$hr$,0$ min: $2\mathrm{.}0\%$ CO$2$

$1$hr$,10$ min: $2\mathrm{.}2\%$ CO$2$

$1$ hr $20$ min: $1\mathrm{.}9\%$ CO$2$

$1$ hr $30$ min: $2\mathrm{.}1\%$ CO$2$

$1$ hr $40$ min: $2\mathrm{.}0\%$ CO$2$

a$)$ Calculate the flow of gas in pounds per minute at the point of injection if the gas upstream of the point of injection is $100\%$ CH$4.$

b$)$ Unfortunately for you, the gas upstream of the point of injection of CO$2$ already contained $1\mathrm{.}0\%$ CO$2.$ How much was your original flow estimate in error $($in percent$).$
