TANKJKT

Download a Preview


Complete design/rating software for jacketed tanks. Covers many tank geometries and linings. Jacket styles supported include conventional, half-pipe, and dimpled plate coils. Easily handles the calculations for covering the side walls and both heads. Also contains modules for either helical or hairpin submerged coils. TANKJKT contains properties for steam and the most commone heat transfer fluids (along with the ability to add your own). Also takes into account the agitation in the tank. Includes the ability to save your data inputs. Both English and Metric units are included.

Bolt Torque Calculator

Download a Preview


Calculate the torque required to tighten UN inch size bolts such as piping flange bolts to a required level of tension without breaking them. See how much or how little of the torque actually goes into achieving tension in the bolt. See the Mohrs Circle and Ductile Failure Envelope conditions both during tightening and after installation. See the effect of various lubricants and bolt surface finishes. Set up to work with UNC, UN8 and UNF inch size bolts to ASTM A193 and A320 bolt materials but with the ability to deal with other thread types and materials. All of the formulas used are provided in the worksheet and the calculation is presented in both US and SI units.

High Pressure Loss Orifice Calculator

Download a Preview

The calculation of compressible flow through orifice plates at high pressure drop (critical flow) appears to be carried out incorrectly in most instances. This flow condition is often encountered on gas plants, compressor stations and pipelines where orifice plates are commonly used as a cheap and convenient way to regulate blowdown and pressurising rates. Blowdown must be achieved within the time period required to make the plant safe but at the same time without an excessive rate of pressure drop that could damage equipment. A more accurate calculation method is proposed below and should be used to improve the engineering predictions.

PIPESIZE

PIPESIZE is designed to help you quickly and accurately perform line size calculations for liquid or gas flow. Contains a nice database of fluid properties along with the ability to add your own fluids. Perform calculations based on the most economical pipe diameter, a specified diameter, or a target velocity. Easily select the number of fittings and valves for an accurate friction coefficient. Includes selection of insulations. Add your own pipe or insulation data as well. Printable data sheets included. Both English and Metric units available.

Equation of State Gas Properties

Download a Preview


Calculate gas properties using cubic equations of state by providing the process temperature and pressure and basic gas properties generally available from reference books. The calculation uses cubic forms of the Van Der Waals, Redlich Kwong, Soave Redlich Kwong and Peng Robinson equations of state which are fully detailed on the worksheet. Density, Molar Volume and Compressibility are calculated for each EOS. The calculation uses both English and metric units.
