Examples of the WaterSteamPro Custom Units functions used in Microsoft Excel Set dimensions in needed form: Used formula: Pressure (to MPa): 1 =wcuSETCU(1;1000000;0) Temperature (to C): 1 =wcuSETCU(2;1;273,15) Volume (m3/kg): 1 =wcuSETCU(4;1;0) Internal energy ,enthalpy (MJ/kg): 1 =wcuSETCU(6;1000000;0) Entropy (kJ/kg*K): 1 =wcuSETCU(5;1000;0) Pressure: 21 MPa The properties in blue are calculated automatically from the input values in red. Temperature: 300 °C Pressure: 21 000 000 Pa Temperature: 573 K Used formula: Volume: 0,001357905 m3/kg =wcuVPT(C12;C13) Density: 736,4286269 kg/m3 Internal Energy: 1,304947004 kJ/kg =wcuUPT(\$C\$12;\$C\$13) Entropy: 3,205131374 kJ/kg*K =wcuSPT(\$C\$12;\$C\$13) Enthalpy: 1,333463006 MJ/kg =wcuHPT(\$C\$12;\$C\$13) Heat capacity (p): 5,288982099 kJ/kg*K =wcuCPPT(\$C\$12;\$C\$13) Heat capacity (v): 3,030153644 kJ/kg*K =wcuCVPT(\$C\$12;\$C\$13) Saturation temperature: 369,827343 C =wcuTSP(\$C\$12) Saturation pressure: 8,58770833 MPa =wcuPST(\$C\$13) Note: All used functions are defined in Visual Basic for Application's Editor. For call it please press Alt-F11 keys. The another way to use the WaterSteamPro functions is to use the WaterSteamPro Custom Units Excel add-in. Choose menu Tools/Add-ins. In appeared dialog check the "WaterSteamPro Custom Units" and press OK. After that all functions will be viewed in "Insert function" wizard
