This post was last edited by Zaihui Kangqiao on 2017-4-7 at 07:58. The Chemical Engineering Theory section is now launching a \"One Question per Day\" initiative to help everyone reinforce their basic knowledge in chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\". We hope for your active support~~~ Replies to the \"One Question per Day\" initiative can be viewed directly at **; the thread will be closed after 1 day! ! To encourage continued participation from everyone this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: For the absorption of low-concentration gases, the applicable conditions for the analytical method when determining the number of mass transfer units are _____; the applicable conditions for the logarithmic mean driving force method are ________; the applicable conditions for the step graph method are _______, and the applicable conditions for the graphical integration method are _____. The balance line within the operating range is a straight line ； The balance line within the operating range is a straight line ； The degree of bending of the balance line remains low within the operating range ； All kinds of situations.
The balance line is straight within the operating range, the balance line is straight within the operating range, the degree of curvature of the balance line is small within the operating range, various situations
The balance line within the operating range is a straight line； The balance line within the operating range is a straight line ； The degree of bending of the balance line remains low within the operating range ； Various situations
