The textbook Mass Transfer Operations: Theory and Applications K.V. Narayanan B. Lakshmikutty

Step 3: Create a Formula Sheet

As you review the solutions, extract every unique formula used (e.g., N_A = (D_AB * P / RT * z) * ln((1 - y_A2)/(1 - y_A1))). Creating your own formula sheet reinforces memory.

The textbook is a comprehensive guide for undergraduate chemical engineering students, balancing fundamental principles with industrial applications. Author(s): K.V. Narayanan and B. Lakshmikutty. Publisher: CBS Publishers & Distributors Pvt. Ltd.

A gas stream containing 5% ammonia (by mole) is to be scrubbed with water in a countercurrent packed tower. The gas flow rate is 100 kmol/h, and the water flow rate is 200 kmol/h. The tower operates at 1 atm and 30°C. Calculate the outlet gas composition.
