Mechanical Engineering and Technical Calculations

MET-Calc is software designed for website.

MET-Calc is a set engineering and technical calculations according to standards for your day-to-day routines. It will reliably, precisely, and most of all quickly guide you through the design of components, the solution of a technical problem, or a calculation of an engineering point without any significant need for expert knowledge.

The user interface MET-Calc: Most calculations have a similar user interface, the advantage of which is the logical structure of the task from the top to bottom of the results. So, as you are accustomed to doing, if you solve the task with a calculator on a sheet of paper.

Hydrodynamic calculation Howell-Jet valve

The Howell-Jet is a type of valve used for dam outlets. The valve uses a flow-shaped body which moves in the direction of the longitudinal axis inside the valve. The water jet leaving the valve has the shape of a hollow cylinder. Unlike the Howell-Bunger closure, the Howell-Jet has a more complex design that must provide control of the movement of the bypassed element outside the valve.

Hydrodynamic calculation Butterfly valve for pump operation (lattice disc)

Today it is required from the butterfly valve to be able to safely close the piping at maximum flow. When closing from an open position, the disc resists the current flowing. The flow is very complex in this case and in certain opening positions the valve is extensively stressed by hydrodynamic forces. The dynamic effects of the flow are

Hydrodynamic calculation Gate valve (through conduit)

The gate valve is a relatively old and proven type of valve that is most often used to close pipeline.
