!!Greetings from the entire Unit Operation Team!!

www.unitoperation.com is a Complete Site for 34-Year-Graduate Aptitude Test in Engineering (GATE)-Chemical Engineering -Questions and Solutions (1990-2023)- ARRANGED Year-Wise, Subject-Wise and Topic-Wise, Quiz, Professional Engineering (PE) and Job Interview technical questions, HYSYS/UniSim Simulation Training Videos, and Videos on different domains of chemical engineering.

Gate questions and answers (from as early as 1990 till 2023) are given here.  Subject-Wise Gate and Topic-Wise questions and handwritten detailed solutions with appropriate book references, , as per latest GATE Syllabus, have also been compiled to aid in learning each specific subject.

Training Videos on HYSYS/UniSim Simulations, suitable for Final Year undergraduate and post graduate students and industry professionals, and Conversion Factors of different chemical engineering parameters, which are extensively used by students and professionals, have been included in the website.

Multiple-choice questions of varying difficulties are given under each subject section.  These quizzes may be used while studying each subject.

We have added two new sections to the website- Equation bank and Videos (UTube) with Youtube links. These sections are at their initial stages of development and we expect that these sections will mature to a reasonable level soon.

I hope you will benefit from this endeavour. If you find any mistake in solutions or scope of improvement of the website, please write to me. Thanks and best wishes.
