K_GateValve
The K_GateValve(RelRough, fo) function returns the resistance coefficient for a fully-open or partially open non-tapered gate valve as a function of the relative roughness of the piping and the fractional opening (fo), defined as 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_gatevalve(RelRough, fo)
{Solution:
K=4.828
}
