Circumference Formula C = 2πr
Area of a circle A=πr²
Pressure formula Pressure = Force/Area or P = F/A
60 x F /( N/2) where F(frequency is Hz) N is the
number of poles
RPM formula
Example: what is the rotating speed of a three phase
30 HZ 6 pole motor?
60 x 30hz = 1800 1800 •/• 3 poles = 600RPM
Time constant formula in T = RC where T is time in sec. R is Resistance and C is
resistive capacitive circuit Capacitance which is probably is in microfarads
Time constant formula in a T=L/R Where T is time in seconds, L is inductance in
resistive inductive circuit henries and R is reaistance
formula for frequency f=1/T where T is time(period) in seconds
Effective Value (RMS) 0.707 x peak value
formula if given peak
Average Value Formula if .636 x peak
given peak
Peak value if given Peak= AVG/0.636 OR
average Peak= AVG x 1.57
peak to peak value 2x peak value
Peak value when given Peak= 1.414 x Effective or RMS
effective or RMS
Peak to peak value when Peak to Peak= 2.828x RMS
given RMS or effective
