Class Objectives
/Class Outline
Students will have some exercises based on lectures of "Fluids Engineering", "Mass Transfer", and "Powder Technology". Every student should answer the exercises after the explanation of the outline of each problem. The items to evaluation are as follows.
(1) Students can calculate pressure, flow velocity and flow rate in fluid transport.
(2) Students can carry out the pump power calculation and piping design based on Bernoulli's principle.
(3) Students can understand the difference between one-dimensional diffusion and equimolar counter diffusion, and calculate the flux.
(4) Students can calculate the mass transfer coefficient based on two-resistance therory.
(5) Students can derive the balance equation in microelement considering the shell balance of the momentum.
(6) Students can design absorption colomns in gas absorption and desorption.
(7) Students can derive the velocity distribution from Navier-Stokes equation.
(8) Students can design distillation colomns considering vapor-liquid equilibrium.
(9) Students can calculate extraction operation, humidity control, drying, and powder handling.

Suggestions on
Preparation and
Lesson 1: Review of fluids engineering and mass transfer in "Chemical Engineering Fundamentals" before taking the class is necessary.
Lesson 2-14: Enough preparation and review of each class is necessary.
Lesson 15: Review of all class is necessary. 
Requirements It is preferable that students are attending in "Fluids Engineering (K7503030)", "Mass Transfer (K7505030)", and "Powder Technology (K7508030)". 
Grading Method ・Students are required to answer the exercises in each class. If students could not pass the exercises, the exercises become homework and should be submitted by next class.
・Achievement of "Class objectives" will be evaluated based on grade of 60 points for the exercise in each class and 40 points for Last examination. Students will pass when you get 60 points.
NOTE: Late submission of the exercise and low quality of the answer of the exercise will deduce points.
