N_t = (G*d_w^4*x)/(8*P*D^3)+2
This formula uses 6 Variables

Variables Used

Total Coils in Valve Spring - Total Coils in Valve Spring is the total number of coils or turns of spring including the coils at the ends of the spring.
Modulus of Rigidity of Valve Spring - (Measured in Pascal) - Modulus of Rigidity of Valve Spring is the elastic coefficient when a shear force is applied resulting in lateral deformation. It gives us a measure of how rigid a body is.
Wire Diameter of Valve Spring - (Measured in Meter) - Wire Diameter of Valve Spring is the diameter of the wire of a valve spring, which constitutes the coils of the spring.
Maximum Compression in Valve Spring - (Measured in Meter) - Maximum Compression in Valve Spring is the maximum amount of axial deflection in the valve spring.
Axial Force on Valve Spring - (Measured in Newton) - Axial Force on Valve Spring is the force acting at the ends of spring trying to compress or expand it in the axial direction.
Mean Coil Diameter of Valve Spring - (Measured in Meter) - Mean Coil Diameter of Valve Spring is defined as the average of the inner and the outer diameters of the spring of an engine valve.

STEP 1: Convert Input(s) to Base Unit

Modulus of Rigidity of Valve Spring: 98900 Newton per Square Millimeter --> 98900000000 Pascal (Check conversion here)
Wire Diameter of Valve Spring: 5.5 Millimeter --> 0.0055 Meter (Check conversion here)
Maximum Compression in Valve Spring: 34.8 Millimeter --> 0.0348 Meter (Check conversion here)
Axial Force on Valve Spring: 340 Newton --> 340 Newton No Conversion Required
Mean Coil Diameter of Valve Spring: 46 Millimeter --> 0.046 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_t = (G*d_w^4*x)/(8*P*D^3)+2 --> (98900000000*0.0055^4*0.0348)/(8*340*0.046^3)+2

Evaluating ... ...

N_t = 13.8955326799316

STEP 3: Convert Result to Output's Unit

13.8955326799316 --> No Conversion Required

FINAL ANSWER

13.8955326799316 ≈ 13.89553 <-- Total Coils in Valve Spring

Cold drawn steel wire for spring manufacturing

Cold-formed steel parts and products are well known for having greater tensile strength and tolerance to stress and temperature – not to mention the surface finish. Cold drawing is a type of work hardening that affects the material's basic crystalline structure which changes its properties. Talented spring manufacturers apply a variety of techniques to create wire forms and springs such as tension springs and die springs, with different qualities and capabilities for different applications.
