PLC Development Environment Using GX Developer. In the C64 Series, the user PLC development environment is supported using MELSEC PLC. development tool, which is Mitsubishi integrated FA software MELSOFT series (GX Developer). This manual explains system configurations user PLC development environment using GX.
Critical Closing Pressure, Laplaceâs Law and Compliance Critical closing pressure â Pressure at which a blood vessel collapses and blood flow stops Laplaceâs Law â Force acting on blood vessel wall is proportional to diameter of the vessel times blood pressure Vascular compliance â Tendency for blood vessel volume to increase as blood pressure increases â More easily the vessel wall stretches, the greater its compliance
Measurement of the vena contracta is useful in echocardiography, where it describes the smallest area of the blood flow jet as it exits a heart valve. This corresponds to the Effective Orifice Area calculated for heart valves using the continuity equation.he effect is also observed in flow from a tank into a pipe, or a sudden contraction in pipe diameter. Streamlines will converge just downstream of the diameter change, and a region of separated flow occurs from the sharp corner of the diameter change and extends past the vena contracta.
