Groove depth

C = sum of allowances for corrosion, erosion, and any thread or groove depth. For threaded components the depth is h of ANSI B2.1, and for grooved components the depth is the depth removed (plus Vc,4 in when no tolerance is specified). 

In the same manner, grooves for sand-line sheaves shall be made for the rope size specified by the purchaser. The bottom of the groove shall have a radius R, Table 4-6, subtending an arc of 150°. The sides of the groove shall be tangent to the ends of the bottom arc. Total groove depth shall be a minimum of 1.75d and a maximum of 3d, and d is nominal rope diameter (see Figure 4-14, B). 

In determining the minimum required thickness of a piping component, allowances shall be included for corrosion, erosion, and thread depth or groove depth. 

C Sum of mechanical allowances (thread or groove depth) plus corrosion and erosion allowances mm in. 

Fig. 9. (a) Groove depth evolution curves, (b) Groove width evolution curves. When free evaporation and surface diffusion are considered simultaneously, the groove profile evolution increases more slowly and tends asymptotically to a constant value (108). 

This behavior can be correlated with the magnitude of the z-component of the electric field, Ez (see Figure 1.157) [156], This increases with groove depth and is spatially maximal at the ends of the slanted grooves.

Equation 2.37) the leveling power (LP) is defined as the ratio of (r vaiiey - (peak)/ valley The results correspond to deposition of 3 pm of nickel on the planar field, or 0.1 of the original groove depth (source Ref. [58]).
