K_GlobeValve



The K_GlobeValve(RelRough, fo)  function returns the resistance coefficient for a fully-open or partially globe angle valve as a function of the relative roughness of the piping and the fractional opening (fo), defined as the ratio of the minimum flow area to the maximum flow area in the valve. 

Example:
$UnitSystem SI K Pa J 
RelRough=0.001
fo=0.5
K=k_globevalve(RelRough, fo)

{Solution:
K=28.12 
}
