The fan blades on a jet engine make one thousand revolutions in a time of 45.6 ms. Determine the period(in s)

Answer 1

1000 rev / 45.6 * 10^-3 sec = 21929.8 rev/sec

take the inverse of that to get the period in seconds/revolution

45.6 microseconds

.

Answer 2

a) era is the time taken for a million revolution so 80 one.8/one thousand= 0.0818 milliseconds. b) Frequency is the quantity of finished cycles in one 2nd. In a million 2nd there are 12.22 80 one.8 ms. So the frequency is 12.22*one thousand=12220 Hz. c) Angular frequency = 2*pi*frequency = 76780.5 radians.
