Calculate the shape factor if the angle tends to 90 degree?

Calculate the shape factor if the angle tends to 90 degree? Correct Answer 1

The shape factor will tend to unity when the angle tends to 90 degree, this can be proved easily using the following equation 0.5(2+cosΦ)*(1-cosΦ)2. Substitute the value 90 in the place of Φ then we get the required answer as 1.

The rear window of an automobile is made of thick glass i.e. AB = 5 mm and thermal conductivity is 0.8 W/m degree. To defrost this window, a thin transparent film type heating element has been fixed to its inner surface.

Interior air temperature and the corresponding surface coefficient are 20 degree Celsius and 12 W/m2 degree. Surrounding air temperature and the corresponding surface coefficient are – 15 degree Celsius and 70 W/m2 degree. Electric heater provides uniform heat flux
Which of the following statements are true? a. As load increases armature current decreases, regardless of excitation. b. For under and over excited motors, power factor tends to approach zero with increase in load c. With normal excitation when load is increased, change in armature current is greater than in power factor which tends to become increasingly leading. d. Both with under and over excitation, change in power factor is greater than in armature current with increase in load.
