# Fitting and valve losses
# Scope: Local pressure loss with supplied summed loss coefficient.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

coefficient = 3
density = 1000 kg/m^3
velocity = 1 m/s

loss := coefficient*density*velocity^2/2 [Pa]

check pressure loss budget: loss <= 2000 Pa

scenario alternative: coefficient = 2.4
