Calculate DNVGL-RP-F115 pipeline internal and external stationary pressure from elevation using Bernoulli's equation.
The local internal pressure is calculated from the reference pressure and relative elevation. The external pressure is calculated from the water depth. The internal fluid density is assumed constant.
