CALCULATOR MODULE : Beam Vibration Added Mass ±
Calculate submerged beam added mass coefficient and added mass from gap height. Added mass is included in the unit mass for submerged beams to account for the fluid which is displaced by the beam. The added mass coefficient can be calculated in accordance with DNVGL RP F105. The equation is suitable for undamped vibration of circular beams in a still fluid. For other beam profiles use the beam width. The method may not be valid for other profiles (engineering judgment is required). The gap height is measured along the axis of vibration and is assumed to be perpendicular to the adjacent surface. Use the Result Table and Result Plot options to display tables and plots. Refer to the help pages for more details about the tools. References : Shock And Vibration Handbook, Cyril M Harris, McGraw Hill

CALCULATOR MODULE : ASME B31.4 Liquid Pipeline Fluid Volume And Mass ±
Calculate ASME B31.4 liquid pipeline fluid density, fluid volume and fluid mass for two phase gas liquid pipelines, and three phase black oil pipelines (gas water and oil). The two phase fluid calculator can be used for single phase gas, single phase liquid, or two phase gas and liquid. The three phase black oil calculator can be used for single phase oil, single phase water, two phase oil and water, and three phase oil, water and gas. Water cut is the volume fraction of water in the liquid phase (ignoring the gas phase). Gas oil ratio (GOR) is the ratio of gas moles to liquid volume (ignoring the water phase). Gas moles are commonly measured as gas volume at standard conditions, eg SCM (Standard Conditions Meter) or SCF (Standard Conditions Feet).
