D.1.5. Number of Rooms for tutorial work
The number of rooms required for the Tutorial work can be determined by applying the following relationship.
NT = B (TL/ST) where,

NT = Number of rooms required for conducting tutorial classes

ST = Class strength for tutorial. Tutorial batches must have strength of 20 in case

of 1^st and 2^nd year classes, whereas in the case of senior classes it should be

limited to 15. Hence an average value of 17.5 can be assumed.
TL = Total Number of students in the College belonging to all classes of all discipline who attend tutorial classes in the groups of 15 to 20.
B = A factor obtained on the basis of:

1. 
   Average number of tutorial hours per week per class, say 7.0
   
2. 
   Teaching hours per week, say 30.
   
3. 
   Utilization factor say 0.66.
   

B = (7.0) / (30*0.66) = 113.0
