# Seal friction screening
# Scope: Sliding friction from supplied contact pressure, contact area and coefficient.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

pressure = 1 MPa
contactArea = 100 mm^2
coefficient = 0.2
speed = 0.1 m/s

force := pressure*contactArea*coefficient [N]
power := force*speed [W]

check seal friction budget: force <= 30 N

scenario alternative: pressure = 0.8 MPa
