The Low-Pressure Blocks library, added in this release, contains five new blocks that incorporate elevation information:

Constant Head Tank block represents a tank where pressurization and fluid level remain constant regardless of volume change. The block accounts for the fluid level elevation with respect to the tank bottom, as well as for pressure loss in the connecting pipe that can be caused by a filter, fittings, or some other local resistance.
Variable Head Tank block represents a tank with constant pressurization and volume-dependent fluid level. The block accounts for the fluid level change caused by the volume variation, as well as for pressure loss in the connecting pipe that can be caused by a filter, fittings, or some other local resistance.
Resistive Pipe LP block represents a hydraulic pipeline which accounts for friction losses and port elevations.
Hydraulic Pipe LP block represents a hydraulic pipeline with resistive, fluid compressibility, and elevation properties.
Segmented Pipe LP block represents a hydraulic pipeline with resistive, fluid inertia, fluid compressibility, and elevation properties.

These blocks enable additional applications, such as low-pressure fluid transportation system simulation.

The following demos have been added in Version 1.5:

Demo Name	Description
Water Supply System (`sh_water_supply_system`)	The water supply system modeled in the demo consists of three pumping stations located at 45, 25, and 30 m with respect to the reference plane, respectively. All three stations are expected to pump water in a tank located at 61 m. The objective of simulation is to determine steady-state flow rates and pressures.
Fluid Transportation System with Three Tanks (`sh_three_tanks`)	The demo illustrates a classical problem of fluid transportation: to determine flow rates, pressures, and fluid volumes in a system built of three constant head tanks. The tanks are located at different elevations and connected with pipelines combined together in a common node. The pipelines are simulated with the Segmented Pipeline LP block, which accounts for hydraulic losses, fluid inertia, and the head due to different node elevations.
