Diameter of Valve Head given Diameter of Port and Projected Width of Valve Seat Solution

Follow our step by step solution on how to calculate Diameter of Valve Head given Diameter of Port and Projected Width of Valve Seat?

FIRST Step Consider the formula
dv=dp+2⋅w
Next Step Substitute values of Variables
∴ dv=40mm+2⋅3mm
Next Step Convert Units
∴ dv=0.04m+2⋅0.003m
Next Step Prepare to Evaluate
∴ dv=0.04+2⋅0.003
Next Step Evaluate
∴dv=0.046m
LAST Step Convert to Output's Unit
∴dv=46mm
