About

You will be able to

  • Solve one-dimensional steady conduction through plane walls, cylinders and spheres, including critical insulation
  • Analyse fins and transient conduction using lumped capacitance and Heisler charts
  • Find convective heat transfer coefficients from correlations for forced and free convection
  • Calculate radiation exchange between surfaces using view factors and radiation shields
  • Design heat exchangers by LMTD and effectiveness-NTU methods
  • Apply Fick's law and the heat-mass transfer analogy

Who it is for

  • B.Tech Mechanical Engineering students of Semester 5 (AKTU)
  • Students of other universities studying the same subject who want unit-wise coaching

What you need

  • Engineering Thermodynamics and Fluid Mechanics
  • Differential equations of first year mathematics

Questions

Which syllabus does the Heat and Mass Transfer course follow?

It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Heat and Mass Transfer. If your own university's syllabus differs, the centre follows your university syllabus.

Will this help in the university examination?

Yes. Teaching is unit-wise as per the AKTU scheme, with numericals, previous-year question practice, MCQ tests and doubt sessions before the semester exam.

Are heat transfer data books allowed?

AKTU usually permits the heat and mass transfer data book in the exam; we practise numericals with it.
