STEP 1: Convert Input(s) to Base Unit

Torque Transmitted by Coupling: 397500 Newton Millimeter --> 397.5 Newton Meter (Check conversion here)
Outer Diameter of Bush for Coupling: 35 Millimeter --> 0.035 Meter (Check conversion here)
Intensity of Pressure bw Flange & Bush of Coupling: 1.01 Newton per Square Millimeter --> 1010000 Pascal (Check conversion here)
Pitch Circle Diameter of Pins of Coupling: 120 Millimeter --> 0.12 Meter (Check conversion here)
Effective Length of Bush of Coupling: 33.5 Millimeter --> 0.0335 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N = 2*M_t/(D_b*p_a*Dp_pins*l_b) --> 2*397.5/(0.035*1010000*0.12*0.0335)

Evaluating ... ...

N = 5.59437606873694

STEP 3: Convert Result to Output's Unit

5.59437606873694 --> No Conversion Required

FINAL ANSWER

5.59437606873694 ≈ 5.594376 <-- Number of Pins in Coupling
