*** PRESSURE DROP ***
This sheet allows you to calculate pressure drop for liquids and gases along circular pipe.
Pressure loss in piping without any size changes occurs due to friction beetween the fluid and the pipe walls.
For incompressible flow, Darcy equation is used to calculate pressure drop along the pipe.
Another method is used for incompressible flow, infact, the flow of gases in long lines closely approximates isothermal conditions.
*** PUMP ***
This sheet allows you to calculate the perfomance of a pump in terms of absorbed power and efficiency.
Two calculation mode are implemented:
> Check mode – the app calculates: hydraulic head, absorbed power (knowing voltage and current) and pump efficiency.
> Simulation mode – assuming pump efficiency, the app calculates hydraulic head and absorbed power.
*** COMPRESSOR ***
This sheet allows you to estimate the absorbed power of a multistage compressor.
*** GAS TURBINE ***
This sheet allows you to calculate the perfomance of a gas turbine (simple cycle).
Two calculation mode are implemented:
> Check mode – from existing data, the app calculates: compressor and turbine power; compressor and turbine efficiencies; net power to generator; cycle efficiency; combustion temperature.
> Simulation mode – assuming compressor and turbine efficiencies, the app calculates compressor and turbine power; outlet temperatures of compressor and turbine; net power to generator; cycle efficiency; combustion temperature.
Calculations are made under the assumption of air standard Brayton cycle.
*** STEAM TURBINE ***
This sheet allows you to calculate: a)Produced power, b)Specific steam consumption, c)Outlet temperature d)Outlet vapor fraction e) Cooling water flowrate & Condenser duty (if a condenser is present).
Necessary input data are: a)Steam flowrate , b)Inlet steam conditions (P-T), c)Outlet pressure d)Turbine efficiency (due to the no-isentropic expansion of steam along turbine), e) Temperatures of cooling water (if a condenser is present).
*** STEAM EJECTOR ***
This sheet allows you to estimate motive steam consumption of a single stage ejector given the following input data: temperature, pressure, flow rate and gas composition of suction mixture.
*** PACKED TOWER ***
This sheet allows you to estimate %flooding and pressure drop for packed fractionators.
*** AIR COOLER ***
The short-cut design procedure adopted in this sheet, can be used for rough sizing and cost estimating purposes.
The procedure yields estimates of plot area, fan power requirements, and finned surface area for a typical air-cooled exchanger.
*** PROPERTIES ***
This sheet allows you to calculate the following properties for a gas:
– Molecular weight;
– Critical temperature and pressure;
– Acentric factor;
– Heat capacity;
– Thermal conductivity;
– Compressibility factor;
– Vapor pressure.
*** CONTROL VALVES (for liquids) ***
This sheet allows you to calculate globe valve's opening for liquid flow.
It can help you to verify the pressure drop of a globe valve for certain flow condition or to calculate unknown mass flow knowing valve's opening.
*** UNIT CONVERTER ***
A classic unit converter.
