D.1.4. Number of Rooms for theory Classes
The number of rooms required for the theory class can be determined by applying the following relationship.

NL = A (TL/SL) where,

NL = Number of rooms required for the lecture classes

TL = Total number of students in the college.

This number depends on the admissions to different disciplines. (this includes all categories of apprentices in case of workshops)

SL = Class strength i.e. the number of students in the class.

A = A factor obtained on the basis of:

1. 
   Lecture hours per week per class, say 15
   
2. 
   Average teaching hours per week say 30
   
3. 
   Utilisation factor of lecture rooms say 0.66.
   

A = (1 5) / (30*0.66) = 0.75
