Angle of inclination in ceiling fan is positive while in table fan its in negative...leading to air flow in same direction..

Generally we have induction motors for fan.there can be two ways to produce the rotary motion in a motor.Either u move the stator part with the conductors on the stator or rotor with conductors on rotor.so in a table fan the blades are fixed and movement appears to be clockwise.

There is no definitive rule regarding the direction of rotation which is determined how the forces are acting on the electrical coils in the motor of the fan. There are two parts in a fan motor rotor and stator. The stator has magnetic poles which generate magnetic flux. This interacts with the coils...

There is no definitive rule regarding the direction of rotation which is determined how the forces are acting on the electrical coils in the motor of the fan. There are two parts in a fan motor rotor and stator. The stator has magnetic poles which generate magnetic flux. This interacts with the coils on the rotor and applies a couple causing the rotation of the rotor. In a table fan, the blades are fixed to the rotor and the movement appears to be clockwise. In a ceiling fan, the blades are fixed to the stator, hence the movement of blades appear to be anti-clockwise. read less

It may be because the blade of fans is bend in such a way that it pushes air downward and forward when it rotates anti clockwise and clockwise direction respectively.

So that their angular momentum be towards motor.

Dear friends, Please correct me in case I am wrong. I your opinion , what should be the maximum number of students in a coaching class, so that each student can have maximum dedicated time from the attending teacher in the classroom. In present days, cost and time of coaching / tuition matters a lot . The same will be demontrated by the following two examples : Example 1 : Suppose a student pays Rs. 4000/= per month ( 26 days in a month , excluding Sundays ), One hour per day , number of student is only one, then cost of coaching per minute works out to (Rs. 4000/=X 1 Student )/(26 days X 60 min/day ) = Rs.2.56 per min. cost and he will get dedicated time of 60 min. each day to carry on his studies. Example - 2 : Suppose a student pays Rs. 2000/= per month ( 26 days in a month , excluding Sundays ), One hour per day , number of student is 30 in a class, then cost of coaching per minute works out to (Rs. 2000/=X 30 Students in a coaching class ) / (26 days X 60 min/day ) = Rs.38.46 per min. cost and he will get dedicated time of only two min. each day for his studies. The above examples shows that though the monthly fees paid by each student is just half ( Rs. 2000/= see example -2 ) in case of classroom type of coaching as compared to the individual coaching ( Rs. 4000/= see example - 1 ), but on the other side cost of coaching per min. based on true dedicated time is 15 times higher in case of classroom type coaching with mass students than single student coaching. These can be however extrapolated for any number of students in a coaching class. As a result the speed of learning process of a student will be about fifteen times slower in classroom type coaching having mass students in a class ignoring the other factors. However, it may be the choice of the students and parents which option is better for them ? Regards, Sudhansu bhushan Roy.
Sir your calculations are excellent. I would like to add few things. 1. It depends on the student / parents choice at the end. 2. It never implies that effective attention to a student is 2-3 mins, so...
