# Water-hammer screening
# Scope: Joukowsky instantaneous velocity-change pressure; wave speed supplied.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

density = 1000 kg/m^3
waveSpeed = 1000 m/s
velocityChange = 1 m/s

surge := density*waveSpeed*velocityChange [MPa]

check surge budget: surge <= 1.5 MPa

scenario alternative: density = 800 kg/m^3
