var fDesc=new Array(); fDesc[0] = "PipeDrop is an advanced hydraulic pressure drop calculator for liquids, gases, and 2-phase flow in pipes and ducts for Windows (tm) based computer systems. The pressure drop calculations can be in either a laminar or turbulent flow regime. Included are 3 powerful modules for calculating pressure drops for single lines, a pump network, and orifice plates.

Also included in PipeDrop is a collection of 8, indispensable tools which are designed to ease virtually ANY hydraulic calculation. The tools can be instantly used within the context of a PipeDrop calculation or independently for other engineering needs. The 8 tools consist of:
- Liquid/Gas Physical Properties (seamless integration with PhysProps)
- Gas Density Calculation Tool (for vapor/gas calculations)
- Compressibility Factor Calculation Tool (for vapor/gas calculations)
- Flow Rate Conversion Tool (lb/hr, m/s -> ACFM, SCFM, etc.)
- Heat Capacity Ratio Calculation Tool (for real vapor/gases)
- Pipe Fitting Loss Calculation Tool (based on the superior 2-K Method)
- ANSI/ASTM and ISO/DIN Pipe Tables (the same high quality tables as found in EngVert)
- Material Roughness Table Tool"; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
